A 13-year-old boy was seriously injured by a firework that struck his face on Long Island late Sunday night, police said.
The victim was with a group of teens who were setting off fireworks outside of a Deer Park home at about 10:50 p.m. when a mortar exploded in his face, according to police.
The boy, who was not identified, was taken to Stony Brook University Hospital with serious injuries.
Investigators are trying to determine how the teens obtained the fireworks.
