Winehouse arrested on suspicion of headbutting man outside bar

An exhausted-looking Amy Winehouse attended a central London police station yesterday, where she was arrested on suspicion of assault.

The singer, who is said to be the tenth richest young musician in Britain, arrived at Holborn police station shortly after 5pm. Wearing a yellow shirt and grey skirt, she rushed up the steps flanked by minders, ignoring a posse of photographers and reporters waiting near by.

Ms Winehouse is accused, reports suggested, of headbutting a 38-year-old man who tried to hail her a taxi outside a bar in Camden in the early hours of Wednesday, and punching a second man in the face. A Scotland Yard spokesman said: "A 24-year-old woman has been arrested on suspicion of assault after attending a central London police station by appointment. She remains in custody."

A spokesman for the singer confirmed that she attended the station voluntarily to be questioned in connection with an alleged incident in Camden in the early hours of Wednesday.

It is the latest setback for the Brit award-winner whose turbulent personal life has made tabloid headlines for the best part of a year. She was admitted to hospital last August after a reported drink and drugs binge. Fans were shocked to see the Back to Black singer bloodstained and covered in bruises and scratches. Her husband, Blake Fielder-Civil, has been remanded in custody at Pentonville jail since last autumn, accused of trying to pervert justice, and she was recently captured on video apparently smoking crack cocaine at her London home.

The singer, who is recording the theme tune for the next James Bond film, is estimated, in the Sunday Times Young Music Millionaire's rich list, to have amassed a fortune of £10m.
