Winehouse spokesman Chris Goodman said the arrest was connected to a video that allegedly shows the Grammy-winning performer taking drugs at a party in her home in north London.

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 house.

London’s Metropolitan police said a 24-year-old woman was arrested Wednesday on suspicion of drugs possession. Goodman confirmed his client was in police custody.

“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.

Winehouse, famous 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 – meaning no charges were laid but the incident was placed on her record.

Shortly after The Sun published still photographs of the video, Winehouse checked into a London rehab clinic.
