Officers responding to an assault on Tyler Street around 2 a.m. Thursday found a 31-year-old man on the floor of an apartment with Joseph Piotroski hovering over him, police said.

The two men had arrived at the apartment together but during an argument over $13, police say Piotroski grabbed a box cutter and swung it at the man, leaving a 2-inch gash on his chest and causing him to fall to the ground.

Piotroski, 26, of Coadale, Pa., then began punching him in the chest and back, police said.

He was taken into custody and faces aggravated assault and weapons charges.

The man was taken to St. Francis Medical Center for treatment.
