DAUPHIN COUNTY, Pa. — Update: Pennsylvania State Police say they're investigating the fire as a possible case of arson.
Authorities say two-single family homes, as well as a multi-unit row style apartment building were damaged or destroyed by the fire.
All of the buildings were vacant, so no one was injured in the incident.
Authorities also say that there were no smoke detectors inside any of the buildings.
Multiple crews responded to a multi-structure fire in Halifax Township, Dauphin County Wednesday morning.
The fire broke out along the 100 block of Armstrong Street and firefighters responded shortly after 2:30 a.m.
When they arrived on scene, one of the buildings was engulfed in flames and appeared to be spreading to nearby buildings. Officials say the buildings were abandoned and under renovation.
There were about 20 different fire departments working the fire. Firefighters are now making sure that all hotspots are extinguished, and there is still no word on when the scene will be cleared.
Officials say the biggest issue they faced today was lack of manpower.
"It's a struggle for us but we did what we had to do and they got the job done, and everybody is safe, no one got hurt," Matthew Herrold, the assistant chief of the Halifax Fire Department said. "That's the biggest concern for me being in charge, is making sure everybody goes home at the end of the day."
Officials also say nobody was evacuated from nearby residences.
The scene is still active and the Pennsylvania State Police and Fire Marshal are currently conducting an investigation.
