An argument between two men escalated to a "consensual fight" in a common area at a downtown apartment on Saturday night.

Then, a third man came out of his apartment and struck one of them with a hatchet, police say.

The attacker also put two witnesses to the fight in headlocks, according to police. They got free and called police.

Police arrested a 52-year-old man and charged him with assault. They used a search warrant to retrieve the hatchet.

The victim of the hatchet attack was treated at hospital for a laceration to the head.
