Investigators found two methamphetamine labs inside a Bethlehem home on Thursday after a fire broke out at the property, according to police.

Officials with the Bethlehem police and fire departments responded shortly before 12:30 p.m. to a home at 746 Linden St. for a report of smoke and flames coming from the property's third floor.

The fire was called to two alarms before it was extinguished about 15 minutes later. Neighbors reportedly told investigators the building was used as a drug manufacturing facility.

After extinguishing the flames, firefighters found evidence of a meth lab on the home's third floor, according to police. Investigators said firefighters also found evidence of a second meth lab in the home's basement.

After a search warrant for the property was approved, officers with the Pennsylvania State Police Clandestine Lab Response Team responded to collect and process the evidence, authorities said.

Police and fire officials are continuing to examine the scene in an attempt to determine the fire's origin and cause. Police said the investigation into the blaze remains ongoing, and that criminal charges are pending.
