LINCOLNTON, N.C. (AP) — Six migrant workers were intentionally hit by an SUV in a Walmart parking lot in North Carolina on Sunday, police said.

The workers were hit at a Walmart in Lincolnton in what appears to have been an intentional assault with a vehicle, but the Lincolnton Police Department said in a statement posted on social media that the driver’s motives are still under investigation. The workers were taken to a hospital with various injuries, but police said none of the injuries appear to be life-threatening.

Police are asking the public for help identifying the driver and the vehicle, described as an older model black sport utility vehicle with a luggage rack.
