Amy Winehouse's imprisoned husband Blake Fielder-Civil has been beaten black and blue in jail.
Blake, who's on remand at London's Pentonville prison accused of assault and perverting the cause of justice, was whacked by inmates who believed he was carrying drugs.
"Blake's been running scared ever since he set foot inside Pentonville-and now his luck has run out," News of the World quoted a source as saying.
"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," the source added.
The source claimed that Blake was lucky to escape the incident with just a black eye.
"Because Blake is such a high-profile inmate, he's a natural target on the landings," the source said.
"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," the source added.
