Gwinnett County police have made four arrests stemming from last month's  shooting at a "Sweet 16″ party that left five teens wounded.

Police said Kempton Greaves, 17, of Stone Mountain got involved in a dispute at the party on Lock Ness Lane near Snellville. Greaves retrieved a firearm and shot it twice into the air, police said. Then Luis Roberto Borrero, 21, of Snellville took the gun and "fired several rounds into the house, striking and injuring five juveniles," police said in a release.

Borrero is charged with five counts of aggravated assault, three counts of third-degree child cruelty, burglary and discharging a firearm while intoxicated. Greaves is charged with discharging a firearm near a roadway.

The shots rang out about 11 p.m. on Feb. 19 at the party, where about 50 teens had gathered to celebrate a birthday.

Four teens were shot, and another hit by shrapnel. The shooting victims were hit in the leg, foot, arm and buttocks. All five victims, students at Shiloh High School, were treated at Gwinnett Medical Center and released.

Police also arrested two residents of the house hosting the party. Xenia Christopher, 35, and Kenny Madlock, 28, were charged with maintaining a disorderly house.
