Oman’s National Gas Company (NGC) has fired its CEO Goutem Sen due to an alleged case of bribery of a government official, the company announced on the Muscat Securities Market.

NGC’s board members unanimously decided to terminate the contract of Sen, who was detained over the suspected bribes in 2014.

“The board of directors wish to inform that the company has received a reply from the public prosecution regarding the detention of the Company’s CEO,” NGC said in its statement. “The reply received states that the CEO has been accused of bribing a government official.”

NGC bottles and markets liquefied petroleum gas (LPG) supplied from Omani refineries in Muscat and Sohar.

The move is part of a widespread crackdown on bribery in the Omani oil and gas sector that has involved the sentencing of several business leaders and officials.

This included former Oman Oil Company CEO Ahmad al-Wahaibi being sentenced to 23 years in jail for accepting bribes, abuse of office and money laundering.
