Nick Stahl arrested in Los Angeles

Troubled actor Nick Stahl is back behind bars after he was arrested in Los Angeles on drug charges.

The Terminator 3: Rise of the Machines star, who has struggled with substance abuse issues in the past, was taken into custody in the early hours of Friday (28Jun13) after police allegedly found him using Methamphetamine at a Hollywood hotel.

Stahl remained in custody as WENN went to press.

The 33 year old's latest brush with the law comes just one day after he told TMZ.com he was on the road to sobriety after spending time in hospital on an involuntary psychiatric hold.

On Thursday (27Jun13), he said, "(My recovery is) going good. It's a process... Things seems to be (looking up) and I'm just grateful."

Stahl has faced a tough few years - his wife Rosie has reported him missing on several occasions and he checked into rehab last year (12) to conquer his demons, only to quit and vanish again soon afterwards.

He was cleared of his most recent legal run-in, a charge for lewd conduct, in February (13) after allegedly misbehaving while watching an adult movie in a Los Angeles porn store last year (12).
