The 33-year-old
actress was not injured in the accident that took place in Los Angeles Monday but her car wasn't as lucky.
When the car that hit hers took off Barrymore followed it retrieving a licence plate number which she gave to the sheriffs deputies that are working the case.
As of Tuesday morning no arrests have been made.
"It could be dangerous," Los Angeles County sheriff's Sgt. Kristin Aloma said of following someone after an accident. Still, she emphasized that getting a licence plate number is instrumental to tracking down a hit-and-run motorist.
