Two people were hospitalized, officials said, after flames erupted in a Drexel Hill home overnight.
According to fire officials, the pair escaped as flames filled the home before crews responded to the 3800 block of Albemarle Avenue in Drexel Hill, at about 4:25 a.m., following a report of a house fire.
In an update to the incident, officials with the Upper Darby Township Fire Department said that, first responders arrived to find flames pouring from the second floor of the property and they found two occupants of the home who had escaped before firefighters arrived.
The pair were both taken to a nearby hospital where, officials said, they were listed in stable condition.
As of about 6 a.m. on Friday, crews were working at the scene and firefighters could be seen in burnt out windows as they continued moving through the home.
Officials did not immediately say what may have caused this fire but, they said, an investigation is ongoing.
