Amy Winehouse was arrested Wednesday in connection with a January video that allegedly shows her doing drugs at a party at her north London home.
London’s Metropolitan Police said the Grammy winner was released on so-called police bail following several hours of questioning at a police station in the city.
Winehouse’s spokesman, Chris Goodman, confirmed that his client had been arrested Wednesday and held in police custody to answer police questions.
“Amy Winehouse voluntarily attended a London police station today by appointment. She was arrested in order to be interviewed and is cooperating fully with inquiries,” Goodman said in a statement.
“The interview relates to a video handed to police earlier this year,” he said.
Britain’s The Sun tabloid in January published still images from a video that it claimed showed Winehouse inhaling fumes from a small pipe. The images were said to have been filmed during a party at her home.
Winehouse, famous for her hit “Rehab,” has had a turbulent private life. Last month she was cautioned by police for assault after she slapped a man during a night out. That means no charges were filed, but the incident was placed on her record.
Shortly after The Sun published the photographs, Winehouse entered a London rehabilitation center.
Her release on police bail means she has not been charged with an offense, but that officers can recall her for more questioning at any time.
Last month, she was held overnight in a cell but was released without charge after admitting assault by slapping a man.
Winehouse, whose battle against drug addiction has often overshadowed her recording success, is said to be worth an estimated $20 million in the latest Sunday Times Rich List.
She did not attend the Grammy Awards in Los Angeles in February, but still managed five big wins, including record and song of the year for “Rehab” and best pop vocal album for her breakthrough release, “Back to Black.”
