A police report, released Thursday by the Anchorage Police Department, details a brawl at an Alaska birthday party last month involving Sarah Palin's family and describes a knockdown, drag-out affair of sucker punches, heavy drinking, bloody mouths, name-calling and a shirt hastily removed for a fight.

News accounts of the Sept. 6 incident were reported at the time, but the official police report was not released until the Anchorage municipal prosecutor's office said Thursday it will not be proceeding with charges in the case, The Anchorage Daily Newsreports.

Sarah Palin, a former Alaska governor and Republican vice presidential nominee, has remained largely quiet about the incident, referring to it only obliquely on her Facebook page two weeks afterward.

She wrote, "I love my Bristol! My straight-shooter is one of the strongest young women you'll ever meet. I have to say this as a proud mama: right up there with their work ethic and heart for those less fortunate, my kids' defense of family makes my heart soar!"

The report, written by attending officers, recounts the skirmish at an outdoor party attended by several members of the Palin family, including Sarah and Todd Palin, their two daughters, Bristol, 23, Willow, 20, and their son Track, 26.

One of the officers noted a long white limousine, used by the Palins, parked out front when he arrived, and a white male, who turned out to be Track, being led toward it. According to the report, he had blood around his mouth and on his hands and appeared to have an injury under his left eye.

"He appeared heavily intoxicated and he acted belligerent at first, but I was able to get him to step out of the car, and a female, who turned out to be his mother, told him to talk to me," officer John Daily writes.

The report said Track was "angry and intoxicated" and that the officer had a "hard time getting him to calm down."

Eventually, Track told Daily that "some guys were talking rudely to his sisters, making them cry" and that he confronted one of them. He "said he would fight him, so Track took off his shirt to fight."

At this point, Track said, he was "hit from behind and Todd stated that there were two guys attacking Track at this time," according to the report.

Todd, Sarah's husband and Track's father, also told the officer that Bristol "got knocked to the ground by the owner of the house."

Bristol, who the officer said "appeared heavily intoxicated and upset," told officers that the brawl started when her younger sister, Willow, said that a girl had hit her.

Matthew McKenna, who was attending the party, told officers he saw Bristol punch Korey Klingenmeyer, the owner of the house, "in the face six times and he just stood there" before a group of wives tackled her to the ground.

"McKenna went to Bristol, picked her up, and brought her from the yard to the street and put her down," the report said. "At that point, Todd and Sarah Palin were there asking what happened and he told them to leave. Nobody listened, and yet another fight started."

At one point, as police were interviewing witnesses, Todd Palin confronted Klingenmeyer and asked him if "he called his daughter a 'bitch.' " Willow then came up "also got involved flipping (Klingenmeyer) off and getting loud." Officer Ruth Adolf noted that "we eventually separated everyone, and the Palin family ended up leaving."

In the end, McKenna told one of the officers, "the whole thing was one big misunderstanding among friends due to too much alcohol and people talking trash."

No arrests were made, the report said, "due to the fact that everyone involved declined to press charges when spoke to at the incident."

The police report appeared to indicate that Sarah Palin was not interviewed by the officers.
