ALLEGANY, N.Y. — A St. Bonaventure student is charged with aggravated DWI after State Police say he was involved in two separate hit-and-run accidents on campus Wednesday.

Troopers say Nathan Prisella, 19, showed obvious signs of impairment and failed field sobriety tests at the scene. 

Prisella was issued appearance tickets for a later date in Allegany Town Court.
