For the second time in less than a week, Butler firefighters were called to an apartment building where a tenant had left without turning off the stove.

No one was injured in the latest case of careless cooking late Monday night, this time at the Shore Street Apartments.

A neighbor at the building was credited with helping avert a possible fire, according to the Butler Fire Department.

The neighbor shortly before 11:30 p.m. heard the smoke detector going off in one of the apartments and went to check, authorities said. The neighbor opened the unlocked door and saw a skillet on the burner of the gas stove.

Butler police said the unattended pan was “causing heavy smoke.”

The neighbor turned off the stove and removed the skillet, fire officials said. Firefighters got there a short time later and ventilated the apartment. Damage was minimal.

The apartment tenant, an unidentified man, still had not returned home by the time fire crews left about 45 minutes later.

Police continue to investigate, but a report was not completed by this morning.

A telephone call to the maintenance department at the Housing Authority of the County of Butler, which owns the Shore Street Apartments, was not returned this morning.

A city police officer last week put out a fire in the kitchen of a second-floor apartment where the tenant, a 65-year-old woman, left while cooking food on the stove, authorities said.

No one was injured in that fire about 6:10 a.m. Wednesday at the three-apartment building on West Brady Street, across from Dunkin’ Donuts.

Patrolman Nicholas Shulik was first to answer the call and snuffed out the fire by placing a lid on the frying pan atop the electric stove.

Neighbors discovered smoke coming from the apartment and called 911. The smoke detector inside also was going off.

The stove was destroyed but no other damage was reported.
