Police respond to shots fired on Northwestern's Chicago campus, suspects in custody

There are suspects in custody after shots were reportedly fired on Northwestern University's Chicago campus Monday night.

Shortly after 9 p.m., the school posted on its website that Chicago police and Northwestern police had responded to reports of shots fired on the Streeterville campus. The shooting allegedly occurred outside Wieboldt Hall on Chicago Avenue.

Around 9:30 p.m., Northwestern posted an update that the situation on campus "has been secured and is all clear." The school did not provide any further information.

A witness told police that a large melee had started in the street in the 300 block of East Chicago Avenue about 9:06 p.m. when a woman drew a handgun and fired one shot.

An earlier alert to the Northwestern community instructed those on campus to take shelter, "lock and/or barricade doors" and "Run, Hide, Fight" due to an "active threat event."

Chicago police had told FOX 32 they responded to an incident at the school but that there was no active shooter.

No injuries were reported.

This is a developing story. Stay tuned for updates.
