Actress Drew Barrymore chased a hit and run motorist around Los Angeles after the reckless driver smashed into her car and sped off.

The Charlie's Angels star was driving in West Hollywood just before 12pm on Monday when she was rear-ended, reports TMZ.com.

But instead of pulling over to exchange insurance details, the perpetrator made off - forcing brave Barrymore to take vigilante action.

She eventually lost track of the vehicle, but she did at least commit the offending car's licence plate number to memory - and pass on the information.

Police are reportedly investigating the incident, but no arrests had been made as Wenn goes to press.
