COOPERSTOWN, NY — A white schoolboy with a rifle chased a black classmate into a police station across the street from the National Baseball Hall of Fame, shot him and then turned the gun on himself as the lone officer on duty closed in, police said yesterday.

The shooter, 16, was in serious condition after shooting himself in the chin. The other boy, also 16, was hit in the arm and was treated and released.

Authorities are investigating if Friday’s attack was racially motivated. The museum remained open during and after the shooting.
