Strengthening an existing security operation at a high-profile sporting venue, without ever getting in its way.
Client:
A major international sporting venue in a UK city. A high-profile crowded place carrying real terrorist and criminal threat, with the duties of Martyn's Law on the horizon.
Operating environment:
Event days with crowds of up to around 27,500 people, in a busy urban setting served by several nearby rail and underground stations. The risk starts well before the turnstiles.
Engagement:
Three phases over several months, across the build up to the venue's busiest season and the season itself. A hostile reconnaissance location survey, a full security review, and an ongoing covert Behavioural Detection Officer (BDO) deployment with a liaison officer in the control room.
Footprint:
A six-officer covert BDO team and a dedicated control room liaison officer, working inside the venue's own safety and security operation, alongside local police and in-house assets.
Delivery partner:
The covert BDO capability was delivered with Soteria Covert Solutions, a long-standing and trusted partner staffed by government-trained specialists.
Scale covered:
13 event days, with crowds of up to around 27,500 on the busiest of them. Our team at 338 Solutions is made up of highly skilled professionals with diverse backgrounds. We work together to provide our clients with tailored solutions that meet their unique needs. Meet our team and learn more about our individual areas of expertise.
When a major UK sporting venue asked us to look at their security, they were not trying to replace anything. They already had a capable operation, run by people who knew what they were doing. What they wanted was another set of eyes. Someone to see the place the way a hostile actor would, find the gaps, and quietly close them. That is the work I want to describe here, with the venue kept anonymous.
Two things sat behind everything we did. The first was to fit around the venue's existing operation and make it stronger, never to duplicate it or get in its way, and always to work directly for the people in charge. The second was to protect the reputation of the venue and its brand. A good day should be remembered for what happened on the pitch, not for an incident in the crowd or a headline the next morning that undoes everyone's hard work. So every intervention was built to resolve the problem quietly, lawfully and with evidence. People first, and the venue's name protected in the process.
Strengthening an existing security operation at a high-profile sporting venue, without ever getting in its way. High-profile sporting venues are among the hardest places to keep safe. The crowds are large and predictable, the dates are known well in advance, the venue itself is a landmark, and by design it has to let tens of thousands of people through quickly. That openness is exactly what makes a crowded place attractive to anyone who wants to do it harm, whether that is a terrorist doing their homework, an organised criminal working the queues, or someone simply intent on causing trouble.
The risk does not begin at the perimeter. A lot of it plays out on the approaches, at the stations, along the walk-in routes, and in the way the crowd behaves before play starts and after it finishes. And it is rarely spur of the moment. People planning serious harm tend to watch, plan and rehearse first. That preparation is one of the few times their intent becomes visible, and one of the few chances anyone gets to stop it.
Our client understood that a strong guard force and good physical security, on their own, will not spot the person across the road timing the search lanes, or the group working the station. They wanted to see their own weaknesses through the eyes of someone planning against them, and to add a covert capability that could act on what it found. They also had one eye on Martyn's Law, the Terrorism (Protection of Premises) Act 2025, which is working its way towards coming into force and will place new duties on venues like theirs.
We ran the work in three stages. Understand the threat, review the operation, then put a live capability on the ground to act on both.
Phase 1.
Hostile reconnaissance location survey
We started by looking at the venue the way a hostile actor would, from the outside in. We worked through the places a person could stand and watch, film, time and plan against the venue without anyone questioning them: the vantage points, the spots to loiter, the natural routes in, and the transport hubs around the ground. For each one we asked what it gave away, whether that was the search lanes, the queues, VIP and team arrivals, deliveries, the control room, or a weakness in the vehicle defences.
The result was a prioritised report. It set out each location, what it exposed and how serious that was, along with the fixes, from things that cost nothing and could be done that week to larger pieces of work for the longer term. For the first time, the venue could see its own site the way someone planning against it would.
Phase 2.
Security review and report
With that picture in hand, we reviewed the wider security operation and measured it against current good practice and national counter-terrorism guidance. We looked at every part of security and reputational safeguarding through the eyes and mind of a hostile actor. We rated the gaps by risk and set out a clear, practical plan that separated the quick wins from the bigger investments. A document to act on, not one to file away.
Phase 3.
Covert deployment and control room liaison
The last phase turned all of that into a standing capability: a six-officer covert Behavioural Detection Officer team across event days, with one of our people embedded in the venue's control room.
We delivered this alongside Soteria Covert Solutions, a firm we have worked with for years and trust completely. Their operators are government-trained specialists who have spent full careers in this work and now bring it to the private sector. On the ground they run themselves. They are specialists, and the right thing to do is let them get on with it. Around them, 338 handles everything else: dealing with the client, tasking through the control room, and coordinating with police and the venue's own people. That split of roles, built on years of working together, is a large part of why the deployment ran as cleanly as it did.
Behavioural detection comes down to a simple idea. People who are carrying out hostile reconnaissance, or committing crime, tend to behave in ways that do not fit the place they are in. Our officers are trained to notice that, deal with it discreetly, and pass it on. Because the team was covert, the public never saw it, and neither did anyone there to cause harm.
The liaison officer in the control room was what tied it all together. With one of our people in the room, information moved both ways. What the team saw went straight out to police and the venue's own staff to be dealt with, and the control room's cameras, radio and live picture came back in to steer the team on the ground. It also meant we could confirm or rule out something the venue suspected, or had picked up on CCTV, so that whatever they decided to do next was backed by solid evidence rather than a hunch.
We never ran as a separate outfit. The team worked as an extension of the venue's own command, there for the people in charge to point at whatever they needed, making the existing operation sharper rather than sitting off to one side.
The team covered the whole shape of an event day, before the crowd arrived, while they were inside, and after they had gone. It stayed covert throughout, and it dealt with problems before they grew or reached the public eye.
Pushing the security perimeter out to the transport network. The team worked the nearby rail and underground stations, not just the turnstiles. They picked up people concealing drugs, spotted anti-social and racist behaviour before it reached the ground, and flagged individuals who needed a closer search on arrival, so the in-house teams were ready for them.
Counter-terrorism and hostile reconnaissance. Officers identified behaviour that fitted hostile reconnaissance, including people photographing security systems and surveying the site, and passed each one to local police and the venue to handle as they saw fit. This was the survey from Phase 1 brought to life, watching the very spots and behaviours it had flagged.
Ticket touting and fraud. The team spotted touts and fraudulent ticket sales, alerted police, and where a customer had been caught out, followed it up and used the venue's own resources to help them. Sellers were tracked and recorded on photo and video, which gave the venue what it needed to ban them or take further action.
Local crime. Officers recognised established local criminals working the area, from phone snatches to drug dealing, and passed them to police and the venue.
Anti-social, racist and violent behaviour. The team watched for it and gave the response teams early warning, so it could be handled before it boiled over.
Looking after ejected customers. When someone was put out, officers followed them off the premises, covertly and without winding the situation up, to make sure they left safely, got home, and caused no more trouble on the way. A quiet result that protects the person, the public and the venue's name.
VIP and team movements. By reading how the crowd was moving before and after play, the team helped keep VIP and player drop-offs and pick-ups smooth and secure.
Evidence and verification. On top of finding things, the team acted as a covert check, confirming or ruling out what the venue suspected or had seen on CCTV, so that whatever happened next stood on proven fact.
Whatever the venue needed. Because of the liaison setup, the team could be pointed at anything the venue wanted watched, covertly, and in a way that kept a lid on the situation rather than escalating it.
Threat first, not a checklist. Every stage started from the real threat to the venue.
Seen through a hostile's eyes. The reconnaissance survey gave the venue something an ordinary audit never would.
A capability no one could see. Because it was covert, our presence neither reassured the public nor tipped off the people we were there to catch.
The perimeter starts at the station. Working the approaches and transport hubs stopped problems before they reached the gate.
In support, never in the way. The team slotted into the existing operation and made it stronger, working directly for the people in charge.
Information both ways. The liaison in the control room turned what we saw into fast, evidenced action.
More from what was already there. We extended the reach of the venue's own security, stewards and police rather than adding a parallel cost.
Reputation protected throughout. Discretion and de-escalation sat behind every intervention, with one aim: keep a good day out of the next morning's headlines, and let everyone's hard work stand.
A clear, evidenced picture of its weaknesses, seen from the point of view of someone planning against it.
A practical, prioritised plan for closing them.
A live capability that found and disrupted problems on every event day, and reached beyond the perimeter.
Real due diligence and reputational cover. A proactive, evidenced posture that reassures governing bodies, insurers and regulators, and that holds up when it is looked at afterwards.
