This arsenal of firearms is among the dozens of weapons that have been taken off London’s streets during the Met’s latest gun amnesty. Since Monday 45 weapons have been surrendered across the capital as part of the Give Up Your Gun campaign, including shotguns, revolvers, rifles and handguns, Scotland Yard said. Detectives from the Met’s gang unit today urged anyone still in possession of an illegal firearm to hand it in before the amnesty ends on Sunday night.
