Nine youths may have been headed for a fight Friday but their plans were disrupted when police chased them and arrested two on gun possession charges, Hempstead Village police said.

They were on Franklin Street by Newmans Court when an officer noticed one appeared to be hiding a gun, said Sgt. Derek Warner, head of the juvenile aid bureau.

“He believed he saw some type of weapon under the shirt of one of the kids,” Warner said.

The officer chased the youths, who all ran for about a block before police stopped them, shortly after 2 p.m., authorities said.

A boy, 13, was charged as a juvenile for weapons possession under the age of 16, a misdemeanor, Warner said.

A 19-year-old was charged as an adult with two felony counts of criminal possession of a weapon, the sergeant said.

“It looks like they were going to pursue another group,” Warner said. “We prevented something from happening.”

Warner cited the ongoing investigation in declining to release certain details, including whether the guns were loaded and the name of the 19-year-old, who is expected to be arraigned Saturday. Both youths are from Hempstead, he said.

“Any time teenagers have weapons, I want to know where they get them,” Warner said.

Investigators will look into who owns the guns, he said.
