Pittsburgh police say a 71-year-old woman was wounded while knitting inside her home on the city's North Side.

Police spokeswoman Sonya Toler says the woman was shot in the leg at 8:54 p.m. Monday. She was taken to Allegheny General Hospital in stable condition.

Police say officers recovered five shell casings near a basketball court across the street.

The woman told investigators she was sitting in a chair knitting when her front window exploded and she felt an immediate pain in her left leg.

Police are unsure what started the shooting or who the target was.

An investigation is ongoing.
