Actress Drew Barrymore was rear ended in a hit-and-run accident in Los Angeles.

The uninjured Charlie Angels star got investigative after the accident and tailed the felonious driver, copping the license plate number which she turned over to LAPD.

Later, Los Angeles County Sheriff Sgt. Kristin Aloma warned Drew, "It could be dangerous" despite the fact that  getting digits is a big help in nailing hit-and-run offenders.

No arrests in the case have been made yet.
