The man was working inside the Flint Township store around 5:45 p.m. on June 15 when he was assaulted, the local police department said in a weekend press release.
A second person recorded video of the attack, which shows the man, who is black, punch the white store worker in the head, causing him to fall to the ground.
“What’d you do that for?” the injured man is heard asking, as the camera zooms in on the attack.
The man is again seen hitting the employee while he remains on the floor.
Officials have not provided a specific motive in the attack, but the Detroit Free Press pointed to social media posts that indicated one of the men heard the employee use a racial slur while speaking on the phone.
But Macy’s spokesperson, Andrea Schwartz, said in a statement to FOX Business that the assault was unprovoked.
"All the materials from the evening have been reviewed and it is clear that the attack was unprovoked," Schwartz told FOX Business in an emailed statement. "We are working closely with local authorities on this investigation, and will defer any further comments about the case to them, per policy.”
The Flint Township Police Department said in a Saturday release the attacker and the cameraman fled together.
Police are looking to speak with the pair, whom the department identified as being Damire Palmer, 18, and 22-year-old Damarquay Palmer, and take their statements regarding the attack. Both have been classified as persons of interest in the case.
President Trump posted about the incident on Monday night.
“Looks what’s going on here,” he wrote. ”Where are the protesters? Was this man arrested?”
