An 18-year-old man named Jameson Witty was arrested by authorities for allegedly following the tow truck, tasked with carting wreckage from actor Paul Walker's fatal accident, and stealing a part while the vehicle was stopped at a red light. Police say they've spoken with a second suspect who has suggested that he might turn himself in.

The tow truck was assigned to pick up the wreckage and take it to an impound yard for futher investigation, deputies said. The remains of the Carrera GT were being hauled off about 10 p.m. Saturday, they said.

The driver noticed "several" vehicles following the truck as it headed east on Newhall Ranch Road, according to the sheriff's department. Here's what happened next, according to that statement:

At one point the driver of the tow truck stopped at the red light E/B Newhall Ranch Road at McBean Parkway. A witness saw a male exit a vehicle that was following the tow truck. The male grabbed a piece of the wrecked Porsche off the tow truck bed. The male drove away with the stolen vehicle part. The tow truck driver reported the theft to the Santa Clarita Valley Sheriff's Station.

The part was described as one of the red Porsche's removable roof pieces, known as t-tops, cops said.

Detectives say that Witty will likely face charges of tampering with evidence and grand theft. [L.A. Weekly]
