Amy Winehouse's hubby in overdose

Blake is rushed to prison medical block

By Ross Hall

AMY Winehouse's junkie husband narrowly cheated death after a drugs overdose in prison.

Blake Fielder-Civil was rushed to the jail's hospital block when he collapsed in agony after taking what he thought was heroin.

Guards found the 35-year-old writhing in pain and vomiting violently in a cell.

They instantly set off alarms and activated emergency procedures to save his life.

A probe was launched and prison officers found he had taken a drug believed to be heroin, mixed with a toxic substance.

A jail source said: "This was a close call, but he might not be so lucky next time.

"If he carries on taking so many drugs, he'll end up dead before long."

Harm

Blake and six other prisoners took the drug in G Wing of north London's grim Pentonville prison. Within moments they were all sick.

Blake, awaiting trial on charges of attempting to pervert the course of justice and GBH, has been repeatedly warned to quit drugs.

Just days before the overdose he was hauled in front of prison bosses for failing THREE random drug tests. He was locked in solitary as a punishment, but was soon back in search of a fix.

The source said: "He's being very stupid. It's only because everyone reacted so quickly that this dodgy gear didn't do long-term harm."

After failing the drug tests, Blake was banned from all contact with the outside world — leaving him fearful over his relationship with Rehab singer Amy, 24.

She has been inseparable in recent days from another Blake—US photographer Blake Wood. They spent hours alone at a London hotel where Amy has been staying since leaving rehab.

Last night a Prison Service spokesman said: "A small number of prisoners were treated in health care following the consumption of an unknown substance."
