CLEVELAND, Ohio – Eighteen people were shot – including one fatally – late Saturday after a large fight broke out among several motorcycle clubs on the city’s East Side, Cleveland police said.

The incident began about 11:30 p.m. Saturday outside a building on East 93rd Street, between Reno and Way avenues, Cleveland police spokeswoman Sgt. Jennifer Ciaccia said Sunday morning.

Update: Authorities identify Cleveland man killed in shooting that injured 17 others at motorcycle clubs’ party

Officers arriving to the shooting discovered one person, a 48-year-old man, with multiple gunshot wounds. He was pronounced dead at the scene, Ciaccia said.

Cleveland police soon learned that other shooting victims – 17 total – had left the area and were driven to area hospitals for treatment. Those most seriously injured were taken to MetroHealth and University Hospitals, Ciaccia said.

Investigators at the scene learned that the shooting was prompted by a fight at a party with members from several different motorcycle clubs in attendance, Ciaccia said. Some people at the party were thrown out but returned to the venue firing gunshots.

Gunfire was returned by others still at the party, Ciaccia said. Authorities are still working to determine how many shooters were involved. No information on arrests has been made public.

The shooting remains under investigation, Ciaccia said.

Police said the shooting happened at a private club. A Facebook business page for the Cleveland Lyfers motorcycle club lists the address of the shooting as its clubhouse.

CC Black LLC bought the property for $85,000 in 2018, according to Cuyahoga County property records. The one-story brick building was built in 1969, property records say.
