Amy Winehouse's Jailed Husband Threatens Her Dad

AMY Winehouse's jailed husband Blake Fielder-Civil has been sending abusive letters to the troubled singer's father, Mitch, according to reports.

Fielder-Civil is currently serving a 27-month jail sentence at Highpoint Prison in Suffolk, England after he was convicted of causing actual bodily harm (ABH) and perverting the course of justice.

And Blake has reportedly sent Mitch, 57, a six-page poison pen note packed with violent threats.

The letter is now in the hands of the police and solicitors as Mitch figures out what to do.

A source tells British newspaper The Sun, "I could hear Mitch physically shaking when he phoned to tell me about the letter.

"He couldn't even bring himself to read it out loud as it was just too sickening.

"But he told me that Blake described graphic scenes from a horror movie, in which Mitch is the victim.

"Part of Mitch wants to pursue this further with the police, maybe even taking out a restraining order.

"But then he is worried about it all driving a wedge between him and Amy."
