TROY – Two teens were beaten and robbed late Monday on Spring Street, police said.

Police said they got a call for a robbery at 11:15 p.m. Monday on Spring Avenue. Officials said two young male victims were at the scene with facial injuries when they arrived.

Capt. Daniel DeWolf said Tuesday the pair traveled to Troy to purchase some marijuana and were allegedly set upon by a group of four suspects.

"The victims were from Glenville and were certainly surprised by their attackers," DeWolf said.

The victims were threatened with a handgun and a knife and at one point were struck in the face with an unknown object. Both suspects received minor injuries to the face.

Police were alerted to the commotion by a concerned neighbor but many of the suspects fled the scene when police arrived. One of the suspects was seen fleeing into 25 Spring Ave. A perimeter was set up and a search warrant was obtained, DeWolf said. Evidence was found in the house and a handgun and knife were found in the area of the robbery. The handgun turned out to be a starter pistol.

A State Police helicopter was called in to help with the search.

Isaiah L. Bridges, 21, of Highland Avenue was charged with fifth-degree criminal possession of stolen property, possession of an imitation controlled substance and possession of marijuana, DeWolf said. He was arraigned Tuesday in city court.

Three of the suspects remain at large.
