The story seems to still be developing. From the Cape Cod Times:

Police are investigating an alleged hate crime in an incident involving four men early Sunday morning on Pleasant Street in Provincetown.

Two men, who are a couple and who live in Provincetown, were walking toward their home at 12:12 a.m. when they saw a gray sedan driving in the wrong direction on the street, according to Provincetown Police Lt. James Golden. One of the men walking told the driver that the street was one-way, and the incident escalated from there, Golden said.

I will post any updates to the story, as I find out more.
