LONDON--The award-winning British singer Amy Winehouse was arrested Friday in connection with claims that she attacked two men during a boozy night out, Scotland Yard said.

"A 24-year-old woman has been arrested on suspicion of assault after attending a central London police station by appointment. She is currently in custody," a spokesman said in a statement.

Grammy award-winning Winehouse, who has fought a public battle with alcohol and drugs, was not named in line with force policy.

But she was seen by a crowd of photographers and reporters arriving at Holborn police station in a silver people carrier shortly before 5:10 pm (1610 GMT).

Her spokesman said earlier that her appearance was in connection with an alleged incident in the north London entertainment district of Camden in the early hours of Wednesday.

British newspapers said this week that she allegedly attacked two men, head-butting one and punching the other as she tried to hail a taxi.
