Pair accused of stealing parts from Paul Walker crash car
The teenager, identified as Jameson Witty, is being held in custody after being arrested at his LA home. His bail has been set at $20,000 (£12,000).
The second man, who surrendered to police voluntarily, has not yet been named.
Walker, who found fame in the Fast and the Furious film franchise, was killed last Saturday when the Porsche Carrera GT supercar in which he was travelling, left the road and collided with a tree.
His friend and business partner Roger Rodas, who was driving, was also killed, when the car caught fire upon impact.
Crash investigators are currently still trying to determine the exact cause of the accident. They have previously stated that speed was a factor, but are examining whether mechanical failure could have caused Rodas – who was a former racing driver – to lose control of the powerful sports car.
Walker had been in the middle of filming the seventh installment of the Fast and the Furious when he died. Production of that film has since been put on hold.
