LONDON (Reuters) - Troubled soul singer Amy Winehouse will not face charges in connection with video footage that showed a woman bearing her resemblance taking drugs, a police source said on Wednesday.

The 24-year-old recording star was arrested after turning herself in at an east London police station last week.

She had been questioned by detectives for nine hours in relation to a video published by a tabloid newspaper in January that appeared to show a woman resembling the singer smoking what the paper said was crack cocaine.

"Following a CPS investigation into a 24-year-old woman ... no further action will be taken," a police spokesman said.

A spokesman for the Grammy-winning singer said in a statement: "Amy's bail date to return to Limehouse police station has been canceled, bringing this matter to an end."

He added: "Amy is pleased to be able to move on and concentrate on music and particularly looks forward to seeing her fans again at eagerly awaited festival performances this summer."

It was the second time Winehouse had been detained by police during the past two months over separate issues.

Last month, she was held overnight in a cell but released without charge after admitting common assault by slapping a man.

The latest Sunday Times Rich List said Winehouse, whose battle against drug addiction has often overshadowed her recording success, is worth about 10 million pounds ($19.45 million).

She did not attend the Grammy Awards in Los Angeles in February, but still managed five big wins, including record and song of the year for the hit single "Rehab" and best pop vocal album for her breakthrough release, "Back to Black."

Her husband, Blake Fielder-Civil, 25, is due to stand trial in June charged with attempted obstruction of justice and inflicting grievous bodily harm.

Fielder-Civil, who is in custody, denies the charges, which stem from an East London pub brawl in June 2006.
