LANSDOWNE Two 21-year-old women were hospitalized with injuries after a house fire early Tuesday in Lansdowne, Delaware County.

The fire, in the first block of West Stratford Avenue, broke out about 4:30 a.m. on the first floor, Police Chief Dan Donegan said.

Police arrived to see heavy smoke and flames billowing from the first- and second-story windows. They were unable to enter but heard two women inside the three-story home screaming. An officer climbed a nearby tree to get a better sense of where the women were located, Donegan said.

"It was a heavy fire in there," he said.

One woman jumped from the third floor. The other escaped through a door, Donegan said. The women, a daughter of the owners and a friend, were the only people in the home at the time.

Both women were taken to the Hospital of the University of Pennsylvania suffering from smoke inhalation. The woman who jumped was also being treated for back pain. Donegan had no further information on their condition.

The single-family stucco home had moderate to severe fire damage. Four or five companies responded to the fire, which was under control in about an hour.

Donegan said that while investigators do not have an official cause of the blaze, they do not consider it suspicious.
