Sutherland denies 'untruthful' assault reports

Kiefer Sutherland has labelled reports that he headbutted a fashion designer at a New York party as "untruthful", reports People.

The 24 star has been charged with assault after Jack McCollough claimed that he had been headbutted by the actor after accidentally bumping into actress Brooke Shields.

In a statement, his attorney Michael C. Miller said: "We are troubled by the untruthful and self-serving information circulating regarding Kiefer Sutherland and events of last Monday evening.

"We are confident, however, that the investigation being conducted by the Manhattan District Attorney's Office and the NYPD will confirm that Kiefer Sutherland was neither the instigator nor a wrongdoer in this incident."

He added that Sutherland would "not be making any comment...out of respect for this law enforcement process".

McCollough later branded the alleged incident as a "vicious, violent and unprovoked attack".
