Out-of-control boy racers have posted videos on the internet of themselves speeding around south-west London on quad bikes.

One man, with a user name Mikelondon08, submitted a clip to YouTube on May 13 showing a biker speeding recklessly around Wimbledon on two wheels of a quad bike.

Another of his videos, posted on May 11, shows motorbikes riding upright and quad bikes driven on two wheels in Imperial Way, Croydon.

Imperial Way has long been blighted by cruising events where young drivers meet to show off their cars and sometimes race.

In April last year a 21-year-old man narrowly escaped being killed in a four-car smash in Imperial Way.

In May 2004 15-year-old Stefan Corson died after being hit by two cars in Coomber Way, Croydon.

And in August 2003, 20-year-old friends Raymond Ayers and Steve Dawson were killed while driving at a similar event in nearby Purley Way.
