Update: Police Investigation Shuts Down Montauk Highway in Bridgehampton

Update, 4:50 p.m: In a statement released on Tuesday afternoon, Southampton Town police said Montauk Highway was closed in Bridgehampton earlier after police found a man in medical distress at about 1:35 a.m.

A Bridgehampton Fire Department ambulance responded and took the man to the hospital, according to police. His name was not released.

Officers noticed a potentially "hazardous situation in the victim's vehicle" and requested an engine from the Bridgehampton Fire Department and Southampton Town hazardous materials team to respond. 

The highway was closed until the scene was safe, police said.

The Fire Department hosed down the roadway and the vehicle was removed. Montauk Highway is now opened in both directions.

Originally: A portion of Montauk Highway in Bridgehampton was shut down due to a police investigation on Tuesday afternoon. 

A hazardous materials team was called in to investigate "a toxic gas," an officer at the scene said, in a vehicle in front of the Bridgehampton Community House. Police are concerned about a pool of liquid under a black police car, immediately behind a car carrier on the road. 

The road is shut down for eastbound traffic between Butter Lane and School Street and for westbound traffic between Ocean Road and Butter Lane. Crime scene tape has been put up around several vehicles around the community house, down to Bobby Van's restaurant. 

The Southampton Town fire marshal's office was also on the scene with a town police command van.

The Bridgehampton Fire Department was first called to the area around 2:10 p.m. 

A witness said she heard shouting and that the driver of a car carrier was sitting outside the truck and some bicyclists gave him water. He was reportedly conscious, but would not answer questions from police or emergency medical providers. Eventually, he stood up and got on the gurney, she said.

Southampton Town police would not answer further questions.
