SANFORD, Fla. (AP) — A teenage gunman wounded 10 people when he opened fire early Sunday after fighting broke out during a private event at a Florida party venue, authorities said.

A security guard tackled and disarmed the shooter almost immediately, and a second guard handcuffed him until sheriff’s deputies arrived, according to an arrest report from the Seminole County Sheriff’s Office.

None of the victims suffered life-threatening injuries, the sheriff’s office said in a statement. It said 10 people were treated at a local hospital for gunshot wounds, primarily below their waists.

Sunday’s mass shooting underscored the problem of gun violence in America and was the latest example of how law enforcement officials nationwide face increasing difficulty curbing violence as juveniles find easy access to firearms.

A 16-year-old suspect was arrested in the Florida case Sunday and taken to a juvenile detention center. He was charged with attempted homicide, firing a weapon in a public place, using a firearm during a felony and illegal possession of a firearm by a minor.
