DUBAI, United Arab Emirates (AP) — A U.S. Navy officer relieved of commanding a Persian Gulf patrol ship allegedly failed to maintain equipment to the point of exposing “his crew to unnecessary risk,” interfered with an inquiry into his actions and once slept drunk on a bench at a Dubai port, according to a naval investigation.

The accusations against Lt. Cmdr. Jeremiah Daley saw the Navy on March 12 remove him from the USS Typhoon, a Manama, Bahrain-based vessel patrolling a region crucial to global oil supplies where American forces routinely have tense encounters with Iranian forces.
