LAWRENCEVILLE, Pa.—State police say a northern Pennsylvania man was fatally shot after trying to run down a borough police officer.

Investigators say 28-year-old Brian Elwood led officers on a chase early Sunday morning in Tioga County, near the New York border.

Authorities say Elwood ran off the road and was surrounded by police, but struck a cruiser than started toward an officer. That officer opened fire, killing Elwood.

Officials say the incident remains under investigation.
