Fielder-Civil battered and bruised in jail

Amy Winehouse's husband Blake Fielder-Civil has been attacked in jail by fellow inmates because they were convinced he was hiding a personal stash of heroin.

Fielder-Civil is currently behind bars in London's Pentonville Prison, where he is awaiting to stand trial on charges of perverting the course of justice relating to a previous charge of grievous bodily harm.

But the 25-year-old is reportedly struggling to stay clean in jail and has already failed three drug tests - leading other narcotic users to believe he has been smuggling the illegal substance in.

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."
