Four people were killed in a shooting Monday morning on a CTA Blue Line train in Forest Park, police in the west suburban village said.
Police were dispatched to the Forest Park Blue Line station, 711 Des Plaines Ave., at 5:27 a.m. Monday after someone called 911 to report three people shot on a train, Forest Park police said in a statement.
Three people were pronounced dead at the scene, police said, and a fourth shooting victim was pronounced dead a short time later at Loyola University Medical Center in Maywood. The ages and genders of the four were not released by police, and a representative for the Cook County Medical Examiner’s office did not respond to a request from the Tribune on Monday morning.
Forest Park police said a suspect was later arrested on the Pink Line by Chicago police officers and a gun was recovered.
Blue Line train service was suspended between the Forest Park and Austin stations as police continued to investigate.
