With little explanation, the Coast Guard has suspended two of the highest-ranking officers at its base in San Diego, which is among the agencys largest operations on the West Coast.

Capt. James Spitler and Master Chief Petty Officer Michael Dioquino were temporarily relieved of duty, Rear Adm. Joseph Buzzella said in a statement.

The Coast Guard cannot accomplish our missions without the respect and trust of each member, Buzzella said. A safe and professional environment for each member is crucial to the success of our service and we will not tolerate behavior that goes against our core values of honor, respect and devotion to duty.

The announcement was made Friday.

Spitler has been serving as commanding officer of Coast Guard Sector San Diego, and Dioquino has been the commands senior enlisted officer.

The Coast Guard would typically relieve someone of duty if they were the subject of an investigation.

Sector San Diego is responsible for patrolling 120 miles of coastline and 750 miles of the Colorado River, as well as the U.S.-Mexico southwest maritime border, the agency says.

Each year, the agency says the sector saves about 150 lives, participates in roughly 250 search and rescue cases, apprehends about 1,200 people crossing the border illegally and performs safety inspections on more than 600 domestic vehicles.
