LONDON, England (CNN) -- Grammy-award-winning singer Amy Winehouse has been released on bail after her arrest for alleged drug offenses, London's Metropolitan Police said Thursday.
Winehouse, 24, posted bail Wednesday night and is due in court in May, said a police spokesman, who declined to be named in line with policy.
The singer reported to police "by appointment" Wednesday afternoon and was arrested for alleged possession of a controlled drug, police said.
Winehouse is well-known for her song "Rehab," which describes the singer's reluctance to enter a clinic. She won five Grammy awards this year -- three for "Rehab" as well as Album of the Year and Best New Artist.
Winehouse has battled drug addiction and spent about two weeks in a rehabilitation clinic in January.
Her stay there followed the leak of a home video that showed her smoking something in a glass pipe minutes after she was heard saying she had just taken six tablets of the anti-anxiety drug Valium.
The Sun, Britain's top daily tabloid, made the 19-minute video public. It said the video was shot in Winehouse's East London home.
The Metropolitan Police investigated after receiving a copy of the video from The Sun.
Winehouse entered rehab last year. In October, she and her husband, Blake Fielder-Civil, were arrested at a Norwegian hotel for marijuana possession.
Wednesday's arrest was the second time in a week Winehouse has been questioned by police. Police brought her in Friday and issued her with a caution for assault after Winehouse admitted slapping a man in a Camden bar in north London.
"Rehab," a song which describes the singer's reluctance to enter a clinic, earned Winehouse three Grammy awards this year. She won two other Grammys for Album of the Year and Best New Artist.
