LAYTON -- A birthday party turned ugly when one man assaulted another man with a beer bottle, police said.
Layton Police Lt. Shawn Horton said police were called to a fight at 2 a.m. Sunday.
Kenneth Robert Ertmann, 48, is accused of breaking a beer bottle over the head of another man and then continuing to assault him.
Both men had been drinking, Horton said. The victim sought medical attention for his injuries on his own.
Ertmann was booked in Davis County Jail on suspicion of aggravated assault. He has since been released.
The Davis County Attorney's Office is reviewing the case before filing formal charges in 2nd District Court.
