A 17-year-old allegedly opened fire on five suspects who were trying to rob him in Mantua Wednesday night and wounded one of them, Fairfax County police said.

Officers responded to the 9300 block of Tovito Drive around 9 p.m. Wednesday for the sound of gun shots, police said.

An investigation revealed that four of the suspects had approached another 17-year-old acquaintance before the shooting incident and demanded his cell phone, police said. The fifth suspect remained in a vehicle.

The teen complied and was not injured, police said.

The suspects then approached the other 17-year-old and an altercation ensued. During the fight, the teen pulled out a gun and fired several several shots, wounding one of the suspects, police said. The five suspects then fled the scene.

The injured 18-year-old suspect went to to Inova Fairfax Hospital with non life-threatening injuries, police said.

The 17-year-old who allegedly fired on the suspects was arrested and charged with malicious wounding and use of a firearm in the commission of a felony, police said.

The robbery portion of the investigation continues and police said no charges have been filed against the five robbery suspects at this point.
