Armed Police from the Met’s firearms division arrested suspects after an armed robbery of a man in Woolwich.
A member of the public reported the robbery to the police and nearby CCTV captured a group. Police closed in and found an imitation pistol.
Woolwich Riverside ward saw a big spike in weapon-enabled robberies last year though there are signs it has reduced since.
It would have been a different result in Bexleyheath as Bexley Council controversially stopped manning CCTV.
