Troubled singer Amy Winehouse has been arrested on suspicion of drug offences after footage of the star allegedly smoking crack cocaine was handed to British police. The 24-year-old star is currently being questioned at a police station in East London.

It is Winehouse's second brush with the law in as many weeks; she was accused of headbutting a man outside a North London pub on 23 April and later turned herself in to authorities. She escaped with a caution.

Winehouse - who has faced a long and public battle against drugs and alcohol - checked into a rehab clinic in London in January after a video showing her allegedly taking a variety of illegal substances was passed on to British newspaper The Sun. She was also arrested, along with her husband Blake Fielder-Civil, in Bergen, Norway last year on suspicion of possessing cannabis. (wenn)
