CHICAGO (WLS) -- A person is in custody after shots were fired inside a PACE bus on the Bishop Ford Expressway near 130th Street Tuesday afternoon, according to Illinois State Police.
A Pace spokesperson said there was a fight between passengers on the bus and shots were fired around 3:45 p.m.
No one on board the bus was injured, Pace and state police confirmed.
The #353 bus, which services the South Side of Chicago and a number of south suburbs, ended up stopping on the shoulder for about an hour, but no lanes of traffic were blocked.
The bus has initially been taken to the Riverdale Police Department, presumably so law enforcement can interview some of the passengers and retrieve video from the bus's cameras.
It's unclear how many passengers were on board the bus at the time of the shooting.
Two men were seen being placed into the back of a cruiser, but they were not in handcuffs. They were apparently brought to the police station for questioning.
Illinois State Police are asking that anyone who witnessed the shooting or has any knowledge of it to contact ISP by phone at 847-294-4400, or by email at ISP.CrimeTips@Illinois.gov.
Witnesses can remain anonymous.
