Police are investigating a shooting at a Chick-fil-A in Union Township, New Jersey.

Officers responded to reports of a shooting at the fast food restaurant on Route 22 near Gelb Avenue just after 8:45 p.m. Saturday 

A man told CBS News New York his girlfriend works at the Chick-fil-A and said a group of men came into the restaurant and went directly behind the counter, where they fired multiple shots.

A family member of another worker said there was some sort of altercation and that Chick-fil-A employees were injured in the violence.

While police have not confirmed details regarding the incident at this time, there was a large emergency response at the scene late Saturday night.
