The eldest son of ex-Alaska Gov. Sarah Palin was busted for assaulting an acquaintance at his Alaska home — his third domestic violence arrest in less than three years.

Track Palin, a 29-year-old Army veteran, was arrested Friday night at his Wasilla home on misdemeanor charges of fourth-degree domestic-violence assault, interfering with the report of a domestic-violence crime, resisting arrest and disorderly conduct, according to an online dispatch obtained by local station KTVA.

“Investigation revealed [Track Palin] assaulted an acquaintance at his residence,” troopers wrote in the dispatch. “When the acquaintance attempted to call authorities, he prevented her by taking away her phone. While being placed under arrest, Palin physically resisted troopers.”

Track is being held without bail at the Mat-Su Pretrial Facility.

Last December, Palin allegedly threw his dad, Todd Palin, to the floor and hit him repeatedly in the head, leaving him covered in blood and with a liquid oozing from his ear.

Sarah Palin, the 2008 Republican vice presidential nominee, told police at the time that her son was “freaking out and was on some type of medication.”

When cops arrived, they saw the parents fleeing the house in separate vehicles, Todd Palin with blood running down his face and Sarah Palin looking “visibly upset,” the paper reported.

Police confronted Track Palin, who called them “peasants” and told them to lay down their weapons, according to documents obtained by the Los Angeles Times at the time. Eventually, he left the house in handcuffs.

That case is being heard at Alaska’s Veterans Court.

Track was also arrested in January 2016 for domestic-violence assault, following a fight with his then-girlfriend, according to the local report.
