Footage shows the two women pounding the postal worker over the back of the head as they wrestle with her in the street, just yards away from a USPS truck which has a badly dented hood.
‘Bruh y’all hit the mailman, they trying to get that stimulus,’ the man recording the assault is heard saying.
It is not clear what led to the attack, but the bystander filming is heard saying, ‘They hit this mail lady car,’ while giving a close up of the mangled front vents of the USPS van.
Millions of checks for $1,400 are currently flooding through the postal service after Joe Biden last month signed the American Rescue Plan to provide a third round of stimulus checks.
Flint Police confirmed that the postal worker was not badly injured and that one arrest had been made since the incident on Thursday afternoon.
Detectives are continuing investigations and did not confirm whether the attack had been motivated by stimulus checks inside the USPS vehicle.
The footage shows several young men standing by and watching as the women batter the postal worker.
At least two young children are also seen in the background watching on.
An elderly lady, who the cameraman refers to as his ‘granny,’ attempts to intervene but is pulled back by her grandson who warns that she may get hurt.
The beating lasts for at least a minute, from what the video is able to show, before the women relent and clamber back inside a Chevrolet Equinox SUV.
‘Y’all going to jail,’ one of the bystanders tells the women as they start to leave.
The mail woman is seen chasing after their car as they speed away.
Flint, around 70 miles northwest of crime-ridden Detroit, consistently ranks as one of the most dangerous cities in the United States.
The Democrat-run city of 100,000 residents has seen a surge in violence during the pandemic with 61 homicides in 2020, up from 46 the previous year – an increase of around a third.
Flint police confiscated 655 guns last year, an increase of more than 36 per cent on the 415 guns taken off the streets in 2019.
