The men - one from Fenton and the other from Arnold - were waiting in the lobby to pick up people who were in jail when the scuffle began.
The Arnold Police Department turned into a battleground Saturday when two men got into a verbal argument, which escalated into a physical confrontation. The men, who were unrelated, were waiting in the front lobby to pick up people who were already in police custody, said Maj. Nick McBroom, of the Arnold Police Department. After arguing, they started trying to headbutt each other. The 29-year-old Fenton man and the 27-year-old Arnold man were both arrested for peace disturbance. They were booked and released on summonses.
