Amy Winehouse has been bailed after being arrested over her alleged use of hard drugs.
The singer attended a police station in London to answer questions that are thought to be related to a video clip, published in January, of her apparently smoking a pipe.
A spokesperson for the Metropolitan police confirmed a 24-year-old woman from Camden had been arrested at around 13:00 BST on Wednesday and taken to a local police station as a follow-up to evidence passed to them earlier this year.
"The woman attended a London police station by arrangement and was arrested in connection with the alleged possession of a controlled drug," the spokesperson added.
"This is in connection with an investigation connected to footage passed to the Metropolitan Police."
On January 22nd, a video and other still photography of Ms Winehouse apparently smoking crack cocaine was published by the Sun newspaper.
A spokesperson for Ms Winehouse said on Wednesday: "Amy Winehouse voluntarily attended a London police station today by appointment.
"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."
