Amy Winehouse's husband Blake Fielder-Civil is at the centre of a new police investigation after photographs of him apparently taking drugs while in jail have surfaced.
The 25-year-old is currently awaiting sentence in London's Pentonville Prison after pleading guilty to perverting the course of justice and grievous bodily harm (GBH) toward pub owner James King in an incident in June 2006.
Fielder-Civil has previously denied taking drugs in the prison.
But pictures published by British newspaper The Sun appear to show him smoking heroin.
A prison source tells the publication, "Blake takes heroin whenever he can get hold of it. His claims to be clean are a fallacy and it is obvious he remains dependent.
"There is nothing to suggest he won't carry on when he's outside and back with Amy. If she takes him back into her life when she is trying to get clean it will be a recipe for disaster."
In January (08), the same newspaper exposed a video of Winehouse, 24, seemingly smoking a crack pipe in her flat after taking a cocktail of other drugs.
