EUGENE, Ore. -- Police are investigating a report of shots fired near the library in downtown Eugene.

Just after 7 p.m. Thursday, police say two sets of men began fighting in front of the Eugene Library.

The men were apparently members of opposing gang sets, and a shot was fired in the direction of the library during two simultaneous fistfights, Eugene PD said.

One of the shots hit a lower window in the café area, police said.

Those involved in the fight left on foot as EPD units flooded the area, and passers-by moved to safety. The presumed shooter was found leaving the area and a gun was recovered near the scene, the report said.

Police later arrested Randy Dean Cook, 33. He was charged with attempted assault 1, felon in possession of a weapon, and unlawful use of methamphetamine.

At this time, Eugene Police say lab personnel are processing evidence and officers are developing further leads.

Anyone with additional information should contact Detective Burroughs at (541) 862-5868.

In an unrelated but simultaneous incident, a vehicle had driven over a Eugene street tree and into the LCC downtown building just feet from the shooting, police said.

Officers investigated the crash and the lone female driver was arrested for Driving Under the Influence of Intoxicants (alcohol).

"Students and staff from LCC were very helpful to officers investigating both of these chaotic scenes, and EPD thanks those who stepped up as witnesses to each event," the department said in a news release.
