Six migrant workers outside a North Carolina Walmart were struck by an SUV Sunday in what police say was an intentional act.
The migrants were hospitalized with an array of injuries, but none were life-threatening, the Lincolnton Police Department said in a statement.
On Monday, a person of interest came forward and was being interviewed by investigators, interim Chief Brian R. Greene said.
Though the motorist was not being called a suspect, Greene said police have seized a vehicle connected to the incident and a search for the driver was over.
The motive remained a mystery, he said.
The motorist was described Sunday as an older white man. The chief described Monday's person of interest as an older man of Hispanic or Latino heritage.
Officials did not provide a make and model for the SUV, but in security video images distributed by police, it appears to be a dark color, possibly black. Authorities hoped someone would recognize it and report it.
The incident was reported at Walmart at 1:17 p.m., the department said.
"Six migrant workers were hit in what appears to be an intentional assault with a vehicle," it said.
Lincolnton is about 35 miles northwest of Charlotte.
It wasn't clear where the migrants are from. Although authorities believe the act was intentional, they have not said it may have been an alleged hate crime.
