A four-alarm fire that gutted Angelina's Pizza and apartments above it Tuesday morning in Dormont is believed to have started in the pizzeria's kitchen, officials said.
No one was injured in the blaze, which was reported at 5:15 a.m.
Dormont police Chief Jeff Arnold said it was unclear what caused the fire at the building, at McFarland Road and West Liberty Avenue. The Allegheny County fire marshal's office is investigating.
Chief Arnold said it was a "very stubborn fire. We chased it all over the place."
The fire also threatened buildings on either side of Angelina's and both were evacuated. At least one of the buildings may have sustained smoke damage, the chief said.
West Liberty Avenue was closed between Biltmore and Peermont avenues while crews battled the blaze. Chief Arnold said it was difficult to get natural gas service shut off inside the building, causing a delay for firefighters.
Fire crews from Castle Shannon, Dormont, East Carnegie, Mt. Lebanon, Scott, Upper St. Clair and Whitehall responded to the fire.
Francesco Varrati has owned the building since 1989, leasing space to the pizza shop and renting upstairs apartments.
He is retired and lives in Bloomfield. The building is his only source of income, he said.
"It's just a total shock," he said.
