Underwater Dive Unit

2710 West Temple
Los Angeles, CA 90026
213-352-4700

History

The Los Angeles Police Department’s Underwater Dive Unit (UDU) has been in operation since 1957. It was originally assigned to the Criminal Conspiracy section, but in 1990 it was reassigned to Air Support Division. Again in 2000, it was reassigned to the Uniformed Support Division. In 2006, the UDU was moved to Metropolitan Division to increase the unit’s logistical support. Department divers have participated in hundreds of recovery operations in its history and are responsible for the investigation of numerous underwater crime scenes, as well as homeland security sweeps and searches. Divers have recovered significant amounts of stolen property, weapons used in crimes, aircraft, and bodies from various underwater locations throughout the city of Los Angeles.

All UDU members have assigned duties in various other commands within the LAPD and perform the UDU missions as a collateral or ancillary duty. Two of the members, the Assistant Officer-in-Charge and the logistics officer, have a full-time assignment as UDU personnel assigned to Metropolitan Division.

UDU personnel come from a diverse cross section of the diving community, with previous experience from military, commercial and recreational diving. The UDU has four officers trained as emergency medical technicians, eleven certified instructors and most team members are certified rescue divers.

The UDU team personnel breakdown

  • A Lieutenant as Officer-in-Charge and diver, a Sergeant as Assistant Officer-in-Charge and diver and a P-3 as a logistics officer and diver.
  • Twenty-eight underwater investigators/divers assigned in squads.
  • Eight boat operators comprised of two sergeants and six officers.
  • Four Bomb Squad Divers.
  • A Tactical Waterborne Unit comprised of one sergeant and seven officers. These members are assigned to Metropolitan Division, D Platoon.

Underwater Dive Unit Mission

Dive team members routinely dive in the Los Angeles Harbor, the Los Angeles River, City lakes, canals, streams, reservoirs and coastal surf.
