Armed police swarmed London's Canary Wharf on Saturday, and accomplished what Captain America failed to do in his 2014 film: apprehend the Winter Soldier. Or at least someone dressed like the Winter Soldier.

According to the Daily Mirror, London Metropolitan Police responded to a report of a man with a shotgun in the business district, and quickly arrested a 29-year-old at West India Quay station. Although one witness quoted feared he was watching an attempted terrorist attack, it turns out the guy was a cosplayer, likely attending the weekend convention in Brighton.

Police later released a statement saying they believed the weapon to be an air rifle, which was underscored in a tweet from the Canary Wharf Group: "Reports of man with firearm at Canary Wharf are incorrect. Man was carrying non lethal Airsoft hobby equipment."
