Who's A Pretty Boy?

Londoners, do you recognize the most idiotic mugger in the capital? He steals a necklace and bracelet from a 16-year-old youth on the Underground - black on black crime, judging by the chunky jewellery -; then, having made good his escape, dons the stolen necklace and stops to admire his reflection in the nearest security camera! Who's a pretty boy, then? Somebody put this idiot behind bars, please.
