A heated argument between roommates ended with one man stabbing the other, cops said Sunday.

The casualty, 23, was stabbed multiple times in the rib cage during the verbal fight on the front porch of their building on Richmond Terrace in Port Richmond around 11 p.m. on Saturday, authorities said.

The casualty was taken to Richmond University Medical Center but couldn’t be saved, cops said.

The roommate, 22, barricaded himself inside their residence but eventually surrendered to cops. Charges against him were pending.

A knife was recovered at the scene.

The pavement in front of the building was still soaked in blood on Sunday morning.
