Five young men were walking on SUNY Old Westbury's campus early Friday morning when an armed man with a gold "grill" on his lower teeth robbed them of their hoverboard, police said.

According to authorities, three 20-year-olds and two 19-year-olds were walking on South Apple Road when a person driving a tan minivan or small SUV stopped and got out of the vehicle at 1:30 a.m.

The driver showed a handgun and demanded the hoverboard from the students. The students handed over the board and the robber fled the scene in the vehicle in an unknown direction, police said.
