Talkin' bout stupid criminals, check out this mugger in Bromley, London, who actually tried on the stolen necklace and admired his reflection ... on the tram's CCTV lens!
Dc Dan Arundell, of British Transport Police's robbery squad, said: "The CCTV images are very clear.
"It was quite clear that he was checking himself out in the reflection of the CCTV camera.
"The general consensus is that he is not the brightest spark. He was there for a long time and either didn't care or wasn't aware he was being filmed."
