Arrested star Amy Winehouse has been cautioned by the British police after confessing to allegations of assault.The singer, 24, is reported to have headbutted a man outside a pub in Camden, north London in the early hours of Wednesday, after a wild party night out.Winehouse was arrested on suspicion of assault on Friday when she voluntarily turned herself in to authorities at London's Holborn Police Station to be quizzed about the incident. She was held in custody overnight after a doctor ruled she was "in no fit state" to be questioned. But, after explaining her actions to police on Saturday morning, she was released without charge.In a statement, the star's spokesman says, "Amy Winehouse was questioned this morning at a London police station in connection to an incident in Camden in the early hours of April 23, 2008."She admitted to a common assault by slapping a man with an open hand and accepted a caution."Amy was fully co-operative with inquiries and apologized for the incident.She thanked the police for their professional handling of the matter.There will be no further action taken."Amy is looking forward to continuing her work on new music in the studio."The caution means that although Winehouse escaped any formal prosecution, the incident will remain on record and could count against her if she faces any similar allegations in the future.
