A man was shot and killed by a Plymouth police officer inside a local Arby's restaurant Thursday night, authorities said.

Officers were dispatched on a report of a disturbance at the Arby's on Hwy. 55 and Revere Lane around 8:20 p.m., where they had a confrontation with the man said to be causing problems in the restaurant, police said. During the altercation, the man was shot and killed by police.

The Minnesota Bureau of Criminal Apprehension is the lead agency investigating the shooting.

The agency says an officer entered the restaurant and approached the individual causing the disturbance. The officer scuffled with the man and tried to bring him under control. Authorities say at some point the officer shot the man, killing him. The BCA did not immediately say whether the man was armed.

The man has been taken to the Hennepin County Medical Examiner's Office for an autopsy. The officer sustained minor injuries. No one else in the restaurant was injured.

Two hours after the incident, two customers and three Arby's staff remained inside the shop being questioned by investigators, witnesses said.

The parents of one Arby's employee reported that their son called home sometime after 8 p.m. to report a disturbance at the shop and said that someone had died. The son then said he was OK and hung up. The parents, who declined to be identified, went immediately to the shop and were holding vigil outside the parking lot, which had been cordoned off by police.

The dead man has not been identified.

The Hennepin County Sheriff's Office and Plymouth police also were on the scene.
