Troubled pop star Amy Winehouse today arrived at a central London police station to be questioned over an alleged assault.
The singer was driven to Holborn Police Station in a silver people carrier shortly before 5.10pm.
After a wait of at least two minutes, she emerged from the vehicle and walked up the steps into the police station flanked by minders and representatives.
She was wearing a yellow tee shirt and a grey skirt.
She walked rapidly up the steps without saying anything to reporters, photographers and camera crews who had waited for three hours for her arrival, having expected her to be at the police station at 3pm.
Her attendance at a police station follows claims earlier this week that the singer was to be questioned over an alleged assault.
Winehouse, 24, was alleged to have headbutted a Good Samaritan who hailed her a taxi outside a bar. She was also alleged to have punched a second person in the face.
A spokesman for the singer said earlier that Winehouse would be attending the police station today voluntarily, by appointment with the police.
"We understand that she will be questioned in connection with an alleged incident in Camden in the early hours of April 23 2008."
The news comes only a day after it emerged that Winehouse, whose husband Blake Fielder-Civil is in jail awaiting trial on charges of conspiracy to pervert the course of justice, is worth £10 million.
The Rehab singer, whose dishevelled appearance and erratic behaviour has sparked renewed concerns about her wellbeing, failed to turn up to support her husband at a court appearance today. He was further remanded in custody and a provisional trial date was set down for 2 June.
The Brit Award-winner's problems began to spiral publicly last year. She was admitted to hospital last August after a reported overdose of heroin, ecstasy, cocaine, ketamine and alcohol.
Fans were shocked to see the Back to Black singer bloodstained and covered in scratches, wearing blood-soaked ballet shoes, and with bruises to her neck, bandages on her arms and make-up smeared down her face after she quit rehab with her husband.
In February, it appeared that things were turning around for Winehouse, who has been in and out of rehab, when she won five prizes - despite being absent from the ceremony - at the Grammy awards.
The beehived-star, currently recording the theme tune for the next James Bond film, recently received three nominations for the prestigious Ivor Novello songwriting awards.
She became the first artist to receive two nominations for the top prize, Best Song Musically and Lyrically.
