LONDON - 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.
