Wirapol Sukphol, who was seen in a YouTube video in 2013 holding wads of cash on a private jet, returned to Thailand in July 2017 after being extradited from the United States where he had fled.

Wirapol, formerly known by his monastic name Luang Pu Nenkham, was expelled from the monkhood in 2013 after the video surfaced. He was accused of having sexual intercourse - a grave offense for monks - with an underage girl, among other charges.

He later fled to the United States.

A criminal court in Bangkok sentenced Wirapol to 114 years in prison though he will only serve 20 years because Thai law stipulates that is the maximum for someone found guilty of multiple counts of the same offense.

"He committed fraud by claiming to have a special power to lure in people and he also bought many luxury cars which are considered a money-laundering offense," an official at the Department of Special Litigation told Reuters.

The official declined to be identified because he is not authorized to speak to the media.

"The court found him guilty of multiple offenses which resulted in a 114-year jail term when combined, which means he will actually serve 20 years in jail," he said.

Neither Wirapol nor his lawyer was available for comment.

Wirapol faces separate charges of child molestation and child abduction. A verdict, in that case, is expected in October.

Wirapol's high-profile case highlighted a series of sex and money scandals that have rocked Thailand's Buddhist clergy in recent years, resulting in calls for reforms of religious institutions.

The military government that came to power after a 2014 coup has stepped up efforts to clean up Buddhism by arresting monks involved in corruption scandals and through the introduction of a bill that reduces the influence of Buddhism's Sangha Supreme Council - the governing body of Buddhist monks.
