London police clear Amy Winehouse of witness tampering

LONDON -- Police are no longer investigating Amy Winehouse on suspicion of attempting to interfere with a court case involving her husband, her spokesman said Friday.

The 24-year-old singer is not required to return to a police station for further questioning, her spokesman, Chris Goodman, said in a statement.

"Amy is pleased to be discounted from the investigation and thanks the police for their professionalism in their dealings with her," the statement said.

Winehouse was arrested in December after being called to a police station. At the time, she was released on police bail and had been asked to return at a later date for further questioning.

Meanwhile, Winehouse's husband, Blake Fielder-Civil, appeared in a London court Friday on charges of attacking a pub landlord and then later conspiring with him to withdraw as a witness at the trial. He is due to appear again in April.

Winehouse didn't attend court because she was traveling to Paris to perform at a Louis Vuitton party, her spokesman said.

The singer won five Grammy Awards, including best record, best song and best new artist in early February.
