Two men were fatally shot at Navy Pier in Chicago, reportedly by a disgruntled ex-employee who targeted them in a non-public loading dock area.

The victims, aged 47 and 51, worked for a contractor.

Following the incident, Navy Pier was temporarily locked down, with visitors sheltering in place.

Police are still searching for a person of interest, and the shooting is considered isolated, with no public threat, CBS News has reported.
