The order did not give reason for the dismissal but said only that it took immediate effect.
The order was signed by NCPO chairman Gen Prayuth Chan-ocha.
Although no reason was given and no replacement was announced, it was believed that a major reason to dismiss the governor was the tragic incident on the sleeper train last Sunday when a 13-year-old girl student, Nong Gaem, was raped, killed and her body thrown out of the speeding train by a SRT employee catering to the sleeper bogey she was seated.
The incident sparked public outcry and widespread share on the social network calling on the SRT governor to show responsibility to the incident. It also called on the military junta to introduce capital punishment on the rapist murderer.
However the governor ignored and even challenged public criticism by saying his resignation would not help to solve problem, but could be interpreted as fleeing from the problem.
He ordered security beef-up, banned alcohol sales on board the train, and reviewed all new staff recruitment. However this was after the incident.
