Amy Winehouse's jailed husband Blake Fielder-Civil was rushed to the prison medical block this week after allegedly taking a drugs overdose.
Fielder-Civil, who is currently behind bars in London's Pentonville Prison, was found vomiting violently and writhing in pain on the floor of his cell after reportedly taking a potentially lethal combination of heroin mixed with an unknown toxic substance with five other inmates.
A Prison Service spokesperson said, "A small number of prisoners were treated in health care following the consumption of an unknown substance."
Just days prior to the overdose, Fielder-Civil had been sentenced to solitary confinement after failing three random drug tests.
He has pleaded not guilty to charges of attempting to pervert the course of justice and will stand trial in June.
The 25-year-old is accused of attempting to fix the outcome of a previous trial for grievous bodily harm.
