Police are searching for a gunman who opened fire at a group of people in downtown Cleveland, injuring nine people, before he fled.

The shooting occurred at 2:30 a.m. Sunday in the city's warehouse district, police said in a news release. No one was killed, but all nine victims did have gunshot wounds.

Investigators interviewed the victims and are reviewing video evidence. Police have not identified a suspect or given a description of the shooter.

The police department said Sunday morning on Facebook that it is offering a reward of up to $5,000 to people who contact it with substantial information.
