Winehouse's hubby's vile threats to her father

London, Oct 6 : English singer songwriter Amy Winehouse's hubby Blake Fielder-Civil has been revealed to have sent a threatening letter to her father Mitch.

The six-page letter, which is said to contain violent threats and abuse, has been handed over to the police and solicitors.

Mitch is now trying to decide whether he should press charges and risk his relationship with his daughter or let Fielder-Civil off the hook.

"I could hear Mitch physically shaking when he phoned to tell me about the letter," the Sun quoted a close pal of Mitch's as saying.

"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," the pal added.

For Fielder-Civil, this is not the first time that he has written dubious notes from prison, because in July it was revealed how he had been plotting drug-fuelled sex romps with a female lag, and had even hinted at a possible threesome with his wife.
