An 18-year-old man has been arrested on suspicion of stealing parts from the wreckage of the Porsche Carrera in which actor Paul Walker died after a fiery crash.

The Los Angeles Sheriff’s Department said late Thursday that it had arrested Jameson Witty at his home in Tujunga, Calif., and that the arrest of a second man is pending.

According to Santa Clarita detectives, Witty and the other man stole a roof panel off the back of the flat-bed tow truck carrying the wreckage of the Porsche Carrera GT following the crash that killed “Fast and the Furious” star Walker and his friend, Roger Rodas.

According to the sheriff’s report, Witty took the part while the tow truck was stopped at a red light. A search warrant was served on a home in Canyon Country, near where the accident occurred in the Valencia area of Santa Clarita.

Witty was booked Thursday at the Santa Clarita Valley sheriff’s station, with bail set at $20,000.

Sheriff’s officials noted that the investigation into the cause of the crash is ongoing.
