Amy Winehouse to be quizzed over assault claims (Reuters)

LONDON (Reuters) - Troubled soul singer Amy Winehouse was due to be questioned by police on Friday over an alleged assault, her spokesman said.

The Grammy Award-winning singer, whose increasingly troubled private life and battle against drug addiction has overshadowed her recording success, will voluntarily attend a London police station, he added in a statement.

He said it related to an alleged assault in Camden, north London, earlier this week.

Newspaper reports said the 24-year-old singer had punched a 38 year-old man in the street during a night out.

Her police visit came on the same day her husband, Blake Fielder-Civil, 25, appeared at Snaresbrook Crown Court charged with attempting to pervert the course of justice and inflicting grievous bodily harm. He denies the charges.

Winehouse, said to be worth an estimated 10 million pounds in the latest Sunday Times Rich List, had been due to attend her husbands hearing, her spokesman earlier told Reuters.

She was not at court.
