British singer Amy Winehouse has been arrested and is being questioned at a police station in east London, informs BBC News.

"Amy Winehouse voluntarily attended a London police station today by appointment," her rep said in a statement. "She was arrested in order to be interviewed and is co-operating fully with inquiries. The interview relates to a video handed to police earlier this year."

"[She] was arrested in connection with the alleged possession of a controlled drug," a rep for Scotland Yard told Us.

Winehouse, 24, is to be questioned about a video obtained by The Sun newspaper in January. Footage shows her allegedly inhaling crack cocaine.

In January 2008, after being caught on camera allegedly doing drugs, the soul diva, 24, entered rehab.

In April, Winehouse spent a night in jail on a common assault charge.
