A Sayville man was charged Saturday night after stabbing a youth in the back on the beach at Smith Point County Park on Fire Island, Suffolk County police said.

The victim was taken to a hospital for treatment of serious but non-life-threatening injuries, police said.

Alexander Murphy, 18, was on the outer beach at 6:07 p.m. when he stabbed a 17-year-old from Selden in the back with a knife during an altercation, authorities said. Police declined to identify the victim because of his age.

Murphy was also taken to a hospital for treatment of minor injuries, police said.

Murphy was charged with second-degree assault and fourth-degree criminal possession of a weapon. He will be arraigned at First District Court in Central Islip after being released from the hospital, police said.
