Ottawa Police were looking Friday for a suspect they say was involved in a barroom brawl that spilled into the street and led to gunshots Thursday night.

“Basically, it was a three-on-one fight, and one pulled out his gun to chase the other three off,” said Capt. Ron Puterbaugh, an Ottawa Police spokesman.

Police arrested two Ottawa men shortly after 11:15 p.m. Thursday outside Pepper’s Lounge, 111 N. Main St.: a 43-year-old on suspicion of aggravated assault and illegally firing a gun, and a 24-year-old on suspicion of disorderly conduct and battery.

The four men were patrons of the same bar, and the fight stemmed from a construction employment dispute, Puterbaugh said. He said the two men arrested had another altercation July 21.

He said police thought Thursday’s fight began inside and that the 43-year-old man later fired a .32-caliber Derringer twice into the air outside the bar. Several people witnessed the altercation, including people inside the bar and people who were driving past when the shots were fired, Puterbaugh said.

No one was seriously injured, and the man being sought, whom Puterbaugh described only as “a white male,” isn’t suspected of a firearms offense.
