Verne Troyer has been placed under involutary psychiatric hold at a hospital near his home in north Hollywood, TMZ has reported.
Troyer was admitted to hospital earlier this week after friends became increasingly worried about his mental state.
The 49-year-old actor rose to worldwide fame as the evil sidekick of Dr Evil in the Austin Powers franchise. One of Troyer's close friends is reported to have told news outlets he was 'extremely upset, drunk and suicidal'.
In a statement posted to Troyer's official Instagram page yesterday, friends of the star urged the public to keep the actor in their prayers. "Asking you to keep Verne in your thoughts and prayers.
"He's getting the best care possible and is resting comfortably.
"Appreciate the support from family, friends, and fans around the world. We will keep you updated here."
Troyer's mental health has been a cause of concern for some time now. Only last year, the actor checked himself into a rehab clinic to combat his alcohol addiction. He even addressed his problems in a statement which read, "I've been hearing from some concerned fans, so I'd like to address a very personal situation.
"As you know, I've battled alcohol addiction in the past, and while it's not always been an easy fight, I'm willing to continue my fight day by day."
As well as his comic role as Mini-Me in the Austin Powers franchise, Troyer's acting credits include parts in Jingle All The Way, The Imaginarium Of Doctor Parnassus and Harry Potter And The Philosopher's Stone.
