A 24-year-old mixed martial arts fighter was arrested yesterday in connection with a burglary and assault in Nu'uanu.

Jason "Mayhem" Miller was booked on one count of burglary and one count of assault. He was being held in a police cellblock last night pending charges.

Miller, who lives in Las Vegas, was arrested after a woman said a man, identified by police as Miller, broke into her Nu'uanu Avenue home at 6 a.m. yesterday. The woman, Miller's ex-girlfriend, said her new boyfriend was assaulted by the intruder.

Police were called, but the intruder fled. Yesterday afternoon, Miller turned himself in.

In October, Miller defeated Hawai'i's Falaniko Vitale before a crowd of about 7,000 at the Neal Blaisdell Center. He is scheduled to fight "Ruthless" Robbie Lawler for the Icon Sport middleweight championship here in February.
