PHILADELPHIA (CBS) – A man is in police custody after he led police on a short pursuit in an ambulance all while holding a co-worker “against his will.”

According to investigators, the incident began when police spotted the ambulance in an area where it shouldn’t have been. The ambulance, according to authorities, was supposed to be at a hospital in Pottstown for a pick-up.

Police then contacted the ambulance company, NovoCare Ambulance based out of Norristown, to alert them of the situation. The company then contacted one of the employees and asked him his whereabouts.

According to authorities, the man told them he was at one location, but the company was able to track his exact location utilizing a GPS device.

Company representatives then informed the worker to return to the company headquarters in Norristown.

Authorities say the employee did not return back to the business and instead drove off towards his home. Police then began a pursuit of the ambulance.

A second employee that was inside the vehicle reportedly called police and told them he was being held “against his will.”

Police eventually stopped the vehicle at 2nd Street and Cheltenham Avenue in East Oak Lane.

The driver was taken into custody and is being questioned by investigators. So far, no charges have been filed.
