The East Lyme Police Department is located in downtown Niantic, right next to Long Island Sound.
The department is staffed by 22 full time East Lyme police officers as well as one Resident State Trooper, whom acts essentially as the "chief of police" for the department.
There are also two police dogs on staff, and among the 22 officers the department staffs a fulltime detective.
All public records are handled by the State Police Troop E barracks in Montville.
