A fight between two roommates turned bloody early Monday when one slashed the other in the arm, police said.

The incident occurred in an apartment on Ellis Street in the Tenderloin when the 56-year-old suspect confronted his roommate about the rent money. When the roommate refused to pay up, the suspect cut him multiple times on the arm with an unknown object before fleeing the apartment, police said.

The victim was treated at a hospital for minor injuries. No arrests have been reported.
