INSIDE EDITION is learning more about that ugly brawl involving Sarah Palin's family.
One witness, Eric Thompson, says Palin's daughter and former Dancing with the Stars contestant, Bristol, was throwing right hooks that would make a prize fighter proud.
On Good Morning America, he said, "Bristol just reached back and started clocking him and she hit him. She reached way back and caught him right here in the chin. I counted at least six times."
According to another report, "Some in the crowd were trying to restrain Sarah, who was clawing to get involved in the fight."
The drama erupted as Sarah’s husband, Todd, celebrated a joint birthday party with a friend. The Palin’s had arrived at the party in a stretch Hummer.
A witness said Bristol and her younger sister, Willow were wearing shades at the party and "behaved like little Hollywood starlets."
Then, fists started flying when the Palin’s eldest son, Track reportedly got into it with one of his sister Willow's ex-boyfriends. Bristol joined in, punches were thrown, and in the uproar that followed, Todd Palin ended up with a bloody nose.
One outraged partygoer yelled, "This isn't some damned hillbilly reality show!"
Jennifer Castro of Anchorage Police Department told INSIDE EDITION, "They responded to what was being reported as a verbal and physical altercation between about 20 or so different subjects."
Sarah Palin made no mention of the incident when she spoke to Fox News' Sean Hannity on Thursday.
Palin said on her Facebook page: "I was traveling [Saturday]."
One blogger wrote, "Pretty sure you and your family were causing chaos. Saw it happen. Don't fib."
Eric Thompson said on Good Morning America, "I heard Sarah Palin scream out, ‘You know who we are, don't you?’ It was like a Jerry Springer episode.”
Jennifer Castro told INSIDE EDITION, "This case is an open investigation. It is being reviewed by our municipal processors office as well as APD if we are going to pursue any charges."
