Terminator 3: Rise of the Machines star Nick Stahl has gone missing - less than one week after leaving rehab.

The 32-year-old actor - who has a history of drug abuse - checked out of a Californian treatment facility last week against doctors' orders and now he hasn't been seen for the past four days.

"He's been missing for four days. But I don't want to comment any further," his wife, Rose Murphy Stahl, said. His friends and family noticed he was missing last week after he failed to return to his friend's home.

"Now he's disappeared. We can't find him anywhere. He has not made contact with anyone. We are all just desperately looking for him. Everyone just wants him to come home. It's a terrible situation. We are searching, but we've had no solid leads," a source said.

This is not the first time Nick has disappeared for more than a week last month he went missing and then re-emerged and was admitted to a rehabilitation clinic. However, he walked out of the facility and went to stay with a pal.
