"Commander, Coastal Riverine Group (CRG) 1, relieved Cmdr. Eric Rasch of his duties May 12 as commanding officer of Coastal Riverine Squadron (CRS) 3," said a statement issued by the Navy on Thursday.
According to the statement, "Rasch was relieved due to a loss of confidence in his ability to command."
Rasch has been temporarily reassigned to another unit. He was responsible for the training and operational readiness of the 400 sailor squadron. Riverine boats provide maritime security in harbor areas as well as conducting escort support for U.S. Naval vessels.
Capt. Gary Leigh, commander of Command Riverine Group 1, relieved Rasch after his review of the results of the Navy's investigation into the incident.
The detention sparked concerns by senior American officials over the release of video of taken by Iran that showed the sailors with their hands on their heads while being detained at sea.
At the time of the incident, Rasch was assigned as the executive officer of Coastal Riverine Squadron-3, the San Diego-based unit of the detained sailors.
A Navy official says the Navy's investigation of the incident is currently being reviewed by the Navy's U.S. Fleet Forces Command and U.S. Pacific Fleet.
