TWO PEOPLE were fatally shot by police in separate incidents Wednesday in Philadelphia and Chester, authorities said.

About 4:30 p.m., a 27-year-old woman was shot by a Philadelphia police officer on Cherry Street near 56th, in West Philadelphia. Cops had been called to the house because the woman was threatening her mother with a knife, police said. When officers arrived, police said, the woman continued to charge at her mother with the knife, then threatened to stab police, leading one officer to shoot and fatally wound her.

She died in the house, police said, and the knife she had been wielding was recovered there.

That fatal police-involved incident followed another early Wednesday in Chester.

According to the Delaware County District Attorney's Office, a Chester cop stopped a vehicle with three people inside shortly after midnight. The driver, Noahcell Bagley, 30, told his passengers that a warrant had been issued for his arrest and that he was going to run from police, authorities said.

When Bagley fled, the cop pursued him and a subsequent struggle led to the discharge of the officer's gun, prosecutors said. Bagley was hit with gunfire, and was pronounced dead at Crozer Chester Medical Center.

A spokeswoman for the Delaware County D.A.'s Office said that she could not comment on whether Bagley or anyone else in the vehicle was armed. The case remained under investigation by the D.A.'s Special Investigation Unit.
