Michigan Attorney General Dana Nessel said Friday that she is investigating the conduct of Royal Oak police officers who stopped and questioned a black man because a woman said he looked at her suspiciously, an incident that sparked allegations of racial profiling.

Nessel said she has directed her Civil Rights Division to review what happened Tuesday to Devin Myers outside the Inn Season Cafe.

“If ever there are concerns that the civil rights of Michigan residents have been violated, our office stands ready to investigate and pursue such matters," she said in a news release.

Police said the incident stemmed from a 911 call in which the caller said she was uncomfortable because a man was circling her vehicle, staring at her from across the street, and was possibly taking pictures of her and her son.

Myers, 20, of Southfield, told the Free Press he was simply waiting for the woman, who was white, to pull out of her parking space on Fourth Street because he wanted her spot. When she didn't move after awhile, he said, he found another spot elsewhere.

He was walking to the restaurant when an officer pulled up and began questioning him.

Myers was verbally detained for about 19 minutes, according to police officials. He was asked to provide his ID during the encounter. A total of four officers responded to the scene, including at least one supervisor, before Myers was told he was free to go.

A video of the incident was circulated widely on social media.

On Thursday, Royal Oak police announced that a supervisor was disciplined and the officer who was the first to respond will receive remedial training.

Police Chief Corrigan O'Donohue apologized to Myers for how he was treated. He said that what should have been "a very short encounter" was extended when the first responding officer insisted on getting the man's identification. He also said the supervisor did not handle the matter appropriately.
