Three Long Island teens have been arrested after alleged repeated attacks aboard a school bus against a 14-year-old student whom they believed to be gay, police said.

David Spencer, 18, of Valley Stream, Chase Morrison, 16, of Lakeview, and Roy Wilson, 16, were charged in connection with attacks on another boy on a school bus transporting students from the Nassau Board of Cooperative Educational Services High School in Hicksville.

The first of the two attacks took place on Tuesday afternoon when the older teens "stomped and kicked" the victim on his arms, legs, stomach and thigh, leaving bruises and "substantial pain throughout his body," according to police. During the beating the students made disparaging remarks about what they believed was the student's sexual orientation, police said.

Then on Wednesday morning, while on the bus heading to the high school, Spencer and Morrison allegedly made anti-gay slurs to the 14-year-old student while slapping him in the head and face, police said.

A school bus driver and an adult monitor were on the bus both days, and police are still attempting to interview both women to see what actions were taken to stop the attacks, Nassau Police Commissioner Lawrence Mulvey said.
