The family behind Thailand’s most prominent beer empire has been thrown into turmoil after explosive allegations were made by the younger brother of Singha Group heir Hiso Pi, accusing him of prolonged sexual abuse spanning more than a decade.
In a video released on Saturday, Hiso Psi alleged that his elder brother repeatedly assaulted him during his early teens, beginning when he was around 12 to 14 years old. He claimed the abuse continued for roughly 12 years and took place in family residences and other private settings.
Hiso Psi further alleged that he holds audio recordings in which Hiso Pi allegedly admitted to the misconduct. He also claimed that other family members, including their mother, were aware of the situation but failed to intervene.
The accusations have sent shockwaves through Thailand, given that the Singha Group is one of the country’s most powerful business dynasties, built on its leading beer brand and long-standing commercial influence.
Following his public disclosure, Hiso Psi said he became the target of legal action initiated by his mother, who reportedly accused him of ingratitude and of damaging the family’s reputation. She is also said to be seeking to reclaim inheritance assets worth hundreds of millions of baht from their late grandfather.
The controversy is further intensified by Hiso Pi’s high-profile marriage to Thai actress Mild in late 2025. Mild was later reported to be pregnant. Thai media accounts suggest Hiso Psi had attempted to warn her about the allegations before the wedding, but she proceeded with the marriage and reportedly barred him from attending the ceremony.
Hiso Pi is the designated heir to the Singha Group, while his younger brother has established a public profile as a marine conservation activist.
As of reporting time, neither Hiso Pi nor representatives of the family have issued a public response to the allegations.
