According to a representative for Scotland Yard, Amy Winehouse was arrested Friday afternoon (April 25) on suspicion of assault. The 24-year-old singer was due to be questioned by police on Friday, and the Grammy-winning artist voluntarily walked into a London police station to face interrogation.

The charge stems from a recent incident in the north London neighborhood of Camden earlier this week, when Winehouse allegedly punched a 38-year-old man in the street. Tabloid newspaper reports claim the singer hit the man when he got in her way while she was playing pool at a bar. She allegedly head-butted another patron, who was trying to hail her a cab early Wednesday morning.

If convicted, Winehouse — who was expected to be released from police custody within the hour — could be sentenced to six months behind bars.

The news comes on the same day that Winehouse's husband, Blake Fielder-Civil, appeared at Snaresbrook Crown Court to face charges of attempting to pervert the course of justice and inflicting grievous bodily harm. He had denied any wrongdoing, and when he appeared in court Friday morning, Winehouse was nowhere to be found. A June 2 trial date was set during Friday's proceedings, and Fielder-Civil will remain in police custody until the trial starts.

Winehouse's arrest is merely the latest in a string of legal troubles she's faced over the last year. She and her husband were both arrested in the Norwegian city of Bergen back in October, on charges of drug possession, and Winehouse was arrested in London late last year on suspicion of attempting to interfere with her husband's court case. Those charges were dropped in February.
