A car driven by Paris Hilton's 17-year-old brother Conrad crashed into two parked cars early this morning ... this according to the LAPD.
The Hilton car hit several parked cars in Brentwood, CA at around 12:50 AM. Cops say Hilton exchanged information with the owner of one of the vehicles and a witness before leaving.
Law enforcement says Hilton left his car behind, as it was in no condition to be driven. It was eventually towed away.
Conrad Hilton was at the Key Club in nearby West Hollywood last night, before the accident.
A TMZ photog drove out to the scene of the accident this morning and snapped this photo.
