A search is underway in Melrose Park for a juvenile who jumped into the Des Plaines River and did not emerge on Saturday night, authorities said.
The Chicago Fire Department was called to assist at North First Avenue and West North Avenue about 7:05 p.m., according to a media notification.
Illinois State Police also responded to assist after three juveniles apparently jumped into the river and one did not surface, according to Sgt. S. Orta.
The juveniles appeared to have jumped from a nearby railroad in the Thatcher Woods area, Orta said.
The incident happened near a railroad trestle bridge, said Patrick Waldron, a spokesman for Canadian National Railway Co.
The search was expected to resume Sunday morning, authorities said.
