Police in New York and Connecticut are searching for a man who robbed a bank earlier Wednesday in central Greenwich, Conn., and then fleed through Westchester.
They are looking for a white man who robbed the Patriot National Bank at gunpoint at 4:30 p.m.
Westchester County police dispatched its helicopter unit and Special Response Team to assist Port Chester police, according to Kieran O'Leary, the public information officer for Westchester County Police.
Police searched near Home Depot at Midland Plaza and along Interstate-95.
Greenwich police recovered a weapon on an embankment under I-95 during the search.
Police reportedly located a stolen Chevrolet Silverado that may have been connected to the bank robber, and had been taken from a residence on Alto Avenue in Port Chester.
Late Wednesday, members of the New York Police Department recovered the Chevy pickup truck and were searching for the suspect near Boston Post Road in the Bronx.
The suspect entered the Greenwich bank at 100 Mason St., displayed a handgun and demanded cash from a teller, police said. The teller complied with the suspect's demand, and the suspect fled with the money, police said. No one was injured during the robbery.
The suspect was described as: 5-foot-5 to 5-foot-7, with an average build, police said. He was wearing a winter hat, a gray hooded sweatshirt, dark pants and light colored sneakers. The suspect also attempted to obscure his facial feature by applying some sort of dark colored makeup, police said.
After fleeing the bank, the suspect was seen by a witness getting into a vehicle and leaving the area, police said. The vehicle was quickly located by a Greenwich police officer as it entered I-95 southbound at Exit 3, police said.
The officer activated his overhead lights and sirens, but the suspect refused to pull over and engaged the officer in pursuit, police said. Shortly after crossing into New York State, the suspect sideswiped another vehicle and crashed, police said. The suspect immediately fled that crash scene and engaged the officer in a foot pursuit off I-95 and into the Port Chester Police Department's jurisdiction, according to Greenwich police.
