Kiefer Sutherland was pulled over in West Hollywood in the wee hours of Tuesday morning and arrested for suspicion of DUI after allegedly exceeding the legal blood-alcohol limit, TMZ reports. Being the 24 star's second DUI in the past five years, by California law, if convicted, he must serve a minimum of five days in jail.

Sutherland, who was stopped after making an illegal U-turn, was transported to a Hollywood police station and later released on $25,000 bail. Sources tell TMZ he was "cooperative and mellow" while in custody. Sutherland is scheduled to face a judge on Oct. 16.
