Authorities are investigating an incident that happened Sunday evening at a former facility owned by Good Shepherd Rehabilitation in Allentown.

The incident happened sometime before 7:30 p.m. at the building, 850 S. 5th Street. Good Shepherd representatives posted just before 9 p.m. on the network’s Facebook page they were “aware of and cooperating with the Allentown Police Department on an isolated incident.”

Good Shepherd representatives stated the building is no longer operational and the incident doesn’t involve any current patients, residents or employees.

City Police Capt. Christopher Diehl told lehighvalleylive.com Monday morning the investigation is continuing. Authorities planned to release more information about the incident later Monday.

Good Shepherd’s South Fifth Street facility shuttered in summer 2023. That’s when the rehabilitation network moved its hospital to a new 23,000-square-foot, state-of-the-art inpatient facility in Upper Saucon.

The Morning Call newspaper reports the former property currently houses various administrative offices, as well as the Raker Center, a long-term care facility on St. John Street. Independent living apartments neighbor the building along South Sixth Street.
