A Novato man who tried to reconcile with an estranged friend was arrested instead after the rapprochement descended into bottle-throwing and pistol-whipping, a sheriff's investigator said.

Bryce Dalton Richtman, 22, was booked into Marin County Jail on suspicion of assault with a firearm and violating probation. He remained in jail Tuesday in lieu of $50,000 bail.

The incident was reported Monday night at Richtman's residence on Indian Springs Road in rural western Novato. Richtman and his estranged friend decided to meet there for drinks and work out a disagreement from a few years ago, said sheriff's Lt. Jamie Scardina.

At one point, the guest offered to resolve the disagreement by letting Richtman punch him. Richtman took him up on the offer, but apparently went at it with such vigor that the guest decided too much pain was being inflicted, Scardina said.

The guest then counterattacked and started throwing bottles at Richtman. Richtman allegedly retaliated by grabbing a .40-caliber Hi-Point semiautomatic pistol and beating the other man in the head with it, Scardina said.

The alleged victim, 21, called authorities and said he wanted Richtman arrested. Sheriff's deputies contacted Richtman, who corroborated the other man's account of events, Scardina said.

Richtman was taken to jail. The other man declined a trip to the hospital, despite suffering large bumps on his head and swelling around his left eye.

The district attorney's office filed charges against Richtman on Tuesday. A plea hearing was pending.

Richtman owned the gun legally and had purchased it in October, Scardina said. It was unloaded at the time of the incident.
