Assault charges against Canadian actor Kiefer Sutherland over an alleged head-butting incident have been dropped, New York prosecutors announced Tuesday.
The misdemeanour assault charges against the star of TV's 24 have been dropped because the person alleged to be the victim wouldn't co-operate with prosecutors, according to a spokeswoman for the Manhattan district attorney's office.
In May, Sutherland was involved in an incident with fashion designer Jack McCollough outside a Manhattan nightclub. He is alleged to have head-butted and McCollough, injuring him.
The two men issued a joint statement several weeks later saying they had resolved their differences.
Sutherland, the son of actors Shirley Douglas and Donald Sutherland, is currently serving probation as part of a drunk-driving conviction that sent him to jail for 48 days in 2008.
