Authorities in Minnesota are looking for an Instacart driver who allegedly drove over an elderly couple’s groceries after seeing a pro-police sign on their property.

In a press release, the Blaine Police Department said the incident occurred on Dec. 6 after the couple placed a grocery order from a local Cubs Foods through the Instacart app.

After they were notified that the shopper had arrived, the couple went outside to meet them worried that they would get trapped in the snow on the driveway.

“When the couple opened the front door, the delivery driver yelled back at them to check inside of their Christmas wreath. They also reported the driver was driving back and forth in the driveway. Upon checking inside the wreath, they located the receipt from the grocery order with a derogatory message,” the police department said.

“After the delivery driver left, they found that their groceries had been run over in the driveway.”

More details of that “derogatory message:”

The couple also found the receipt from the grocery order with a message saying “Instacart doesn’t pay employees, sry find another slave. F— the racist police pigs.”

The driver is currently interacting up close and personal with the local PD: “The driver has not been arrested or charged with a crime, but she could face misdemeanor charges of disorderly conduct and criminal damage to property, which can send her to jail for up to 90 days.”
