Amy Winehouse to be quizzed by police

Troubled British singer Amy Winehouse is to be quizzed by police over an alleged trial-rigging plot by her husband Blake Fielder-Civil.

The 'Rehab' singer, 24, will be questioned under caution, and will be required to give DNA samples. She will also be required to have her fingerprints taken.

Blake Fielder-Civil is currently in locked up in London's Pentonville prison, where he awaits trial for assault, and now Amy is to be questioned on her own potential involvement in the case.

"Amy's had her problems but she's really terrified this time," says a pal. "She's teetering on the brink.

"If they're both handed lengthy jail sentences she's determined they'll end it together rather than face years apart.

"She can't live without Blake. Her family are worried sick."

A Scotland Yard source told Britain's News Of The World newspaper: 'This is a very significant development.'

Blake was originally arrested after an alleged incident at the Macbeth public house in Hoxton, east London, last June.

Barman James King, 36 - who was seriously injured - was allegedly offered a $400,000 bribe to change his story.

Meanwhile, Civil-Fielder's mother Georgia, who has previously criticized her daughter-in-law, has vowed that her son's current incarceration will mark the end of his marriage with Winehouse, telling the paper, "He can't go back to her. That will be over my dead body.

"I only care about my son. I'd sell my soul to the devil to have him back. That's how I feel. I'm bashing my head. I just want to hold him."
