Maryland authorities arrested two people on Thursday after a patron fired a gun at restaurant security guards following a dispute over a bill, police said.

The incident occurred around 12:40 a.m. when Montana Artis, 21, and Tony Smith, 19, were customers at the Cadillac Ranch Great All-American Bar and Grill, according to Fox 5 DC. The pair were believed to be having an issue with employees about their check, the Prince George’s County Police Department said.
