Police continued to search the scene Wednesday following a police-involved shooting that left a detective shot accidentally by fellow officers.

Police cordoned off the area in Bushwick as they combed the street for evidence that could lead to clues about the location of a third suspect believed to be involved in the incident.

Two undercover narcotics officers were attempting to make an arrest Tuesday around 6:15 p.m. when they stopped a van as part of a buy-and-bust operation targeting suspected heroin dealers.

They say the driver of the van, 46-year-old Oscar Vera, allegedly stepped on the gas, causing the car to go into reverse and smash into a police cruiser. Police say Detective John Gladstone reached into the car and attempted to make an arrest.

While Gladstone was halfway inside the car, Vera allegedly attempted to drive away, prompting another officer and a sergeant to open fire. Subsequently, police say Gladstone was shot in the arm by the sergeant.

He was taken to Elmhurst Hospital and is in stable condition, police say.

Vera was shot in the leg and the wrist and placed under arrest. He was taken to Bellevue Hospital, where he is in stable condition. Police say he has 58 prior arrests.

Police say 51-year-old Geraldo Rodriguez was also taken into police custody. Police say he has 17 prior arrests.

A third person fled the scene, according to police. Police say all three men are suspected of involvement in a heroin deal.

Police say they are searching for surveillance video that may have captured an image of the third suspect.
