A Long Island teenager has been arrested on a charge of setting another teen on fire.

Nassau County police say the 17-year-old is scheduled to appear in First District Court in Hempstead on Tuesday on a felony assault charge.

Investigators say the incident occurred over the weekend as a group of friends stood near a backyard fire pit at a home in Wantagh. The accused teen allegedly doused the victim's back and legs with lighter fluid. Police say he also squirted lighter fluid into the pit.

Police say the victim's clothing caught fire. He's being treated for second- and third-degree burns at Nassau University Medical Center.
