Anchorage prosecutors have declined to file criminal charges over a booze-fuelled brawl involving the family of former Alaska governor Sarah Palin at a birthday party, police said as they released a report describing the melee. The Palins made world headlines after the fight, which erupted at an outdoor party late on September 6 between revellers there and Palin's husband Todd, son Track and daughters Bristol and Willow, according to an Anchorage police report released on Thursday. Sarah Palin, a former Alaska governor and the 2008 Republican nominee for United States vice-president, was present at the site of the brawl when police arrived, but the report does not describe her as physically involved in the melee. The Anchorage prosecutors office declined to file charges in connection with the incident, said Jennifer Castro, a spokeswoman for Anchorage police. She did not say why prosecutors decided against charges. After the fight, Track, 26, appeared "heavily intoxicated" and was "belligerent at first" when officers found him inside a white limousine used by the family, according to the 25-page police report. Shirtless, with blood around his mouth and an eye injury, Track told an officer that some men were "talking rudely to his sisters, making them cry" and that one of the men punched his friend, sparking a fight. Police said that in a separate scrum, home owner Korey Klingenmeyer pulled Bristol Palin, 23, across the lawn by her legs while calling her crude names. A witness told police that Bristol appeared "heavily intoxicated" and punched Klingenmeyer five or six times. A representative for Sarah Palin did not immediately respond to requests for comment. Partygoer Matthew McKenna said "the whole thing was one big misunderstanding among friends due to too much alcohol and people talking trash".
