Police are confirming that rehab singer Amy Winehouse will face no more action over the conspiracy charges leveled at her jailed husband Blake Fielder-Civil. Police quizzed Winehouse last December over allegations she attempted to pervert the course of justice, before releasing her on bail and warning her she'd be asked to return to the police station for more questioning. But police on Friday announced the star will play no further part in their investigation. Meanwhile, Fielder-Civil was forced to confront judges in London on Friday without the support of his wife, who didn't show for his court appearance. There was no sign of the singer as Fielder-Civil took the stand at Snaresbrook Crown Court to plead not guilty to the conspiracy charge. He has already denied causing grievous bodily harm with intent to London pub landlord James King. In a bizarre twist, Fielder-Civil was then charged with teaming up with King to pervert the course of justice.Fielder-Civil has been remanded in custody until a directions hearing on April 25th.
