Washington (CNN) A former commander at US Naval Station Guantanamo Bay, Cuba, was arrested in Jacksonville, Florida, on Wednesday and charged with obstruction of justice, concealment, falsifying records and making false statements during an investigation into the death of a civilian worker who drowned near the base in 2015.

Navy Capt. John Nettleton is accused of interfering with a probe related to the death of Christopher Tur, a loss prevention safety manager at the facility's Naval Exchange who was found dead in waters near the military facility on January 11, 2015, according to the indictment returned by a federal grand jury.

An autopsy revealed that Tur had suffered injuries prior to his drowning.

At the time of Tur's death, Nettleton was the commanding officer of the naval base at Guantanamo Bay but not the detention facility at the same location.

He has been charged with two counts of obstruction of justice, one count of concealing information, two counts of falsifying records and five counts of making false statements.
