Special Constable Matt Kerr is used to fighting crime - but he has now turned his hand to infiltrating buildings and breaking into vaults.
The gaming fan turned virtual challenges into reality when he had to lead a team in an experience based on the new game Battlefield Hardline.
Matt has now scooped £10,000 after his crew won the adrenaline-fuelled competition, by successfully avoiding being caught by patrolling guards.
The 22-year-old, from Grimsargh, was registered into the contest after pre-ordering Battlefield Hardline last month.
He said: “A week later I got a phone call saying I needed to assemble a team of five people in 48 hours and then head down to London.
“The detail was very, very vague. We were thinking it could be paintballing or laser tag but we had no idea.”
We had to secure a VIP, secure a hard drive, break into the vault and steal as much loot as we could
The team was given a briefing in London and Matt said: “We had a Skype conference with a so-called Mafia boss who told us to infiltrate a building.
“We had to secure a VIP, secure a hard drive, break into the vault and steal as much loot as we could.
“The fourth objective was to get out without being caught.”
Matt, who works as a special constable for Lancashire Police, said: “It was very authentic, highly enjoyable. We located it, completed the objectives, and got out in 27 minutes with three minutes to spare.
“There were 45 teams in total, each with five people, and 30 trial teams before it.
“I certainly don’t enter any competitions so it was a shock to see we had won.”
Matt said he would be sharing the cash with his team mates.
Dan Sheridan, EA UK social and community marketing manager, said: “You could tell Matt’s crew The Usual Suspects meant business as soon as they arrived.
“They hadn’t travelled all the way from Preston just to take part.
“Matt had assembled a great crew and they communicated really well once inside the experience.
“We couldn’t believe how much they took from the vault!”
