Amy Winehouse voluntarily handed herself into a London police station on Friday (April 25) after she was accused of headbutting a man who attempted to help her hail a taxi.
The singer was outside of a bar in the London suburb of Camden on Wednesday night, when a scuffle broke out with Winehouse alleged to have punched a second man in the face.
Winehouse, 24, handed herself into Holborn police station and is expected to remain there overnight.
