Forest Park, Illinois: A shooting on a subway train outside Chicago on Labor Day morning left four people dead, police said.

Three people were pronounced dead at the Forest Park station, an above-ground stop on the Chicago Transit Authority's Blue Line. The fourth victim died at a hospital.

The suspect got away but was subsequently arrested on a train on a different route, Forest Park police said.

"A weapon was recovered,” Forest Park Deputy Chief Chris Chin told reporters. "There is no immediate threat. This appears to be an isolated incident on this unfortunate day.”

Police were called around 5:30 a.m. Chin said he had no immediate information to disclose about the victims. He called the shooting "shocking” and "horrible.”
