Arsenal fans are have been urged to be vigilant on matchdays following reports of fans being targeted by knife-wielding moped gangs.
Security has been tightened around the Emirates Stadium and the club’s official fan club has contacted members to urge them to keep mobile phones out of sight.
Islington was last year named the second worst borough in London for moped-enabled crime, behind Camden.
In an email, the team’s national supporters’ club said: “One supporters’ club member was robbed at knifepoint yesterday before the game by two people on a moped. Unfortunately this crime is a fairly common event in the Islington area these days, so keep your phone in your pocket if at all possible or at least be aware of your surroundings when making that call.”
Businesses near the stadium also warned that moped gangs had been targeting tourists and fans. Murat Eric, 32, manager of Little Wonder Café, said one of his chefs had fallen victim.
He added: “There are so many tourists round here who always have their phones out, taking pictures with the statues, and the gangs target them.”
Another shop owner said: “A woman came in crying last week very upset after a gang on bikes came and threatened her and took her phone.”
An Arsenal spokesman said: “We would always encourage people to be vigilant and to report anything suspicious.”
