Four police officers have been filmed stopping a 20-year-old black man on the street after a white woman called 911 because he 'looked suspiciously' at her.

Devin Myers was stopped and questioned by police in Royal Oak, Michigan on Tuesday when he was trying to go into a vegetarian restaurant.

A Facebook Live video shot by a bystander showed Myers being surrounded by at least four officers on the sidewalk just outside the restaurant.

The woman who filmed the video claimed a white woman had called the officers after Myers looked at her while he was parking his car.

'This young man is stopped because a Caucasian lady said that he looked at her suspiciously and he has been pulled over walking going to eat by two police officers for suspicion of being black,' the woman said in the video.

She repeatedly said the woman who had dialed 911 was sitting in her white car across the street watching the incident unfold.

Myers, who remained calm throughout the ordeal, could be heard apologizing to the officers for wasting their time.

The two officers who initially responded said they were waiting for a supervisor to come to the scene after Myers objected to be questioned.

Myers told all four officers that it was evident he was not a threat to the woman.

'You pull up and you see, I'm not a threat to her. I'm not even close to her,' Myers said.

The owner of the restaurant, who was a white woman, stood up for Myers by telling officers repeatedly there was no problem and suggesting race was an issue.

The young man was eventually told he could leave the scene.

The supervising officer told the restaurant owner that she was inferring a lot from the 911 call.

He added that Myers should have just told the woman that he was minding his own business parking his car.

The restaurant owner insisted that's what Myers did but the woman called police anyway.

None of the police officers were identified but the department said they were investigating.
