Someone started a fire on a Chicago Transit Authority L car early Saturday, temporarily shutting down service in the Loop, authorities said.
An unknown male started the fire that caused minor damage to an Orange Line car just before 1 a.m. near the first block of West Van Buren Street, according to Chicago police, who called it an arson. The fire-starter took off, police said.
Loop-bound Orange Line trains were stopped for nearly two hours near the Harold Washington Library, according to CTA service alerts.
Service has resumed. No one was hurt.
