CHICAGO (CBS) — Chicago Transit Authority Blue Line service was suspended for hours Sunday night, after someone was hit and killed by a train.

A person was struck by a train late Sunday at the LaSalle Blue Line subway stop, at LaSalle Street and Ida B. Wells Drive.

Police said a man jumped in front of the train and his death was a suicide.
