An investigation is underway after crews pulled a vehicle from the Connecticut River in Middletown overnight.
Police and firefighters responded to the Connecticut River at River Road and Eastern Drive after a caller reported hearing a car go into the river and seeing taillights as they submerged.
Police attempted to search the vehicle and boats were deployed to search the area from the surface.
Investigators said dive team members from multiple departments initiated a dive operation from the shore. Police used a drone and firefighters used thermal imaging cameras to look for occupants from the shore, they added.
No one was found in the SUV. Police said they believe whoever was in the car made it to shore and took off.
Crews removed the car from the river and monitored the vehicle during the removal to make sure no fuel was leaking into the river, authorities said.
