Video: Coolest crime fighter ever - caught on CCTV
This is the moment have-a-go-hero helped police capture a sprinting suspected drug dealer while he was arm-in-arm with his girlfriend.
A teen suspected of dealing Class A drugs was giving at least three officers the slip until a passer-by stopped him in his tracks in Clarance Street, Kingston. The smartly-dressed man casually stuck out a well-timed leg to bring the suspect down at around 11.20pm on Saturday when officers pounced on him. The Met Police said officers arrested a 17-year-old man on suspicion of possessing with intent to supply Class A drugs.
