Actor Tom Sizemore has been spared jail after his lawyers convinced a Los Angeles judge that prescribed medication made him fail a drugs test.

The Black Hawk Down actor, 44, was deemed to have violated conditions of his probation, which dates back to a 2004 drugs offence, when a routine test discovered amphetamines in his urine.

Sizemore has already spent three months in a rehabilitation clinic for his addictions, and the court has declined the prosecution's request to jail the star - if he can provide a prescription to prove his claims.

Sizemore is currently on bail, pending his appeal over his conviction for domestic violence against former lover, Hollywood madam Heidi Fleiss.
