Amy Winehouse Video Checked by Police

WEDNESDAY JANUARY 23, 2008 08:20 AM EST

Police in London are studying the video that allegedly shows singer Amy Winehouse smoking crack, they confirmed Wednesday.

On Tuesday, the U.K.'s Sun ran stills from the tape, which shows the troubled chanteuse, 24, smoking what the paper claims in a crack pipe.

Now detectives at Scotland Yard are looking at the footage, the police confirmed to PEOPLE. (Despite claims the tape had been "seized," officers were, in fact, handed a copy of the video by reporters from the tabloid yesterday.)

As of now there is no investigation launched into the singer, a spokesman added. "Officers will be reviewing the footage and will then assess the footage and ascertain whether any action is to be taken."

Shortly after the news of the alleged drug use surfaced, Winehouse (who's gone back to her burnette roots after a short stint as a platinum blonde) was photographed leaving her East London home for an appointment with her doctor – something her rep told PEOPLE was part of her ongoing treatment.
