British singer Amy Winehouse has been arrested on suspicion of drug offences, police sources say.

The Grammy-winning soul singer, who was released with a caution for assault less than two weeks ago, was being held after she handed herself in at a London police station.”At 1pm (2200 AEST) on Wednesday, a 24-year-old woman attended a London police station by arrangement,” police said in a statement. “She was arrested in connection with alleged possession of a controlled drug.”

Police declined to give more details.

Winehouse was held overnight in a cell last month but was released without charge after admitting assault by slapping a man with her hand. Winehouse, whose battle against drug addiction has often overshadowed her recording success, is said to be worth an estimated STG10 million ($A20.77 million) in the latest Sunday Times Rich List.

Winehouse 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 ‘Rehab’ and best pop vocal album for her breakthrough release, Back to Black.
