John Slettehaugh, 67, of Minneapolis, the alleged victim, told officers he saw "a group of kids being rowdy" as they seemed to be leaving the train. One of them went over to Slettehaugh and grabbed his hair, the report said.

Slettehaugh then said he told them to "keep your hands off me," and then called them a racial slur. The report notes he "regretted it for saying it afterwards."

The report states that Slettehaugh claimed to have been hit seven or eight times and that officers saw a laceration on the left side of his head and across his forehead.

Slettehaugh described the suspects as a group of eight black teenagers between ages 14 and 16, although he couldn't offer any further description, according to the report.

The report identifies a second victim 27-year-old Antonio McKinney, although it does not say how he was involved.

The case is still under investigation.
