Amy Winehouse's incarcerated hubby Blake Fielder-Civil was attacked in jail because his fellow junkie inmates were convinced he was hiding a stash of heroine from them.
A source tells British newspaper News of the World, "He got ambushed by a few blokes who thought he had heroin on him. He's been put in solitary three times already for failing drug tests so they figured it was a fair bet he'd be carrying some although he wasn't.
"Because Blake is such a high-profile inmate, he's a natural target...There have been lots of threats and for a long time he just kept himself confined to his cell - he'll be staying there a lot more now."
Amy tried to visit him last week but she arrived so late, she was refused. Duh! That's why they're called visiting hours.
