Amy Winehouse may be arrested by police over claims she punched a woman at a charity event.

Sherene Flash, 30, claims Winehouse lashed out after being asked to pose for a photo in London last month.

According to the Sun newspaper, Winehouse failed to appear at a police station in London last Wednesday to answer questions about the incident.

Police are said to have told the singer’s agent that she may arrested if she misses another scheduled appointment.

A friend of the singer told the newspaper that because of Winehouse’s personal problems it’s “hardly surprised she missed the interview.”

The incident is said to have take place at The End of Summer Charity Ball in Berkeley Square where Winehouse made a surprise appearance.
