Indonesia national under-23 football team also known as Indonesia Sub-23 or Garuda Muda, was accused of match fixing during its game against Thailand and Vietnam during the 2015 Southeast Asian Games in Singapore this month.

The Jakarta Legal Aid Institution (JLAI) called a press conference on Tuesday to reveal a phone recording that allegedly proved match-fixing claims. The evidence showed came from a whistleblower, who was a part of an underground gambling mafia operating in Indonesia, Singapore, and Malaysia.

The conversation was recorded on June 14 between the whistleblower and the Malaysian bookie, in which the latter confirmed that the match between Indonesia and Vietnam in the SEA Games was being influenced.

The bookie said that the Indonesia Sub-23 would lose by more than 4 goals, with the match ending 5-0 to Vietnam.
