Southampton police divers are searching the Peconic River for a handgun believed to used in a recent rash of armed robberies that have spanned the North Fork.
Police also have three men in custody whom they believe are responsible for at least four separate stickups in Riverside, Riverhead and Mattituck over the last month, said Southampton police Sgt. Lewis Scott, who was on the scene Wednesday morning.
Members of the Southampton Town Dive Recovery Unit started scouring the river behind McDonald’s in Riverside about 10:30 a.m. after receiving information that the handgun used in the robberies was dumped in the water, Sgt. Scott said.
Even if police recover a gun, they will keep searching the river bottom until they’re confident every inch had been covered, he added.
Police have not yet released the names of the men in custody.
