The heir to the Singha Thai beer empire has been fired after his brother posted a tearful video accusing him of sexually abusing him starting when he was 12.

Sunit “Pi” Scott was fired Tuesday after his younger brother Siranudh Scott, 29, made the disturbing allegations in a tearful video on May 9, claiming he’d recorded his brother confessing.

Siranudh alleged that he’d been abused for more than a decade, saying he’d been forced to perform oral sex on his brother several times — while lashing out at their parents for failing to protect him.

“I don’t want anyone to call me a Singha heir. People don’t know the truth,” the younger brother sobbed in his video of his shame at his family’s behavior.

“Everyone in my family knows it because they listened to the tape I recorded of his ‘confession’ but no one took action.

“I don’t know what to do. I know I cannot live like this. I don’t want to stay in a family that doesn’t value me or have empathy for me. I can’t live with these kinds of people.”

He directly addressed his brother, saying, “What you did to me… many times over the years, when you were 14 or 16. Pi, that affected me.”

Sunit has strongly denied the claims but admitted some incidents with his brother were “rough,” Thaiger reported.

“The claim about the sexual assault is untrue. Everyone who knows me can confirm that I would never do such a thing, as it is disgusting and terrible,” he said.

Sunit said he and his brother argued but strongly denied there was any sexual abuse.

Sunit was “dismissed” from all of his roles at Boonrawd Brewery Company, which started in 1933, making it the oldest brewery in Thailand.

The founding family has a net worth of $1.75 billion.

Bhurit Bhirombhakdi, the brand’s CEO and the brothers’ cousin, said the company expressed ” its deepest regret to Siranudh Scott for what happened.”

The company said it’s cooperating with the authorities.
