Police in the Central Highlands province of Dak Nong on Tuesday arrested a man for allegedly abetting bribery in a corruption case that he himself had exposed.
Tran Minh Loi, 48, known by many in his province as an active whistle-blower, will be detained for three months pending investigation.
Colonel Truong Ngoc Lep, deputy police chief of Dak Nong, said Loi will be investigated for his role as "an accomplice" of some gamblers who bribed some police officers in exchange for their release.
On January 15, police in Dak Mil District reportedly arrested six people for gambling.
After the gamblers were taken to a police station, Lanh Thanh Binh, an officer of Dak Mil Police, allegedly suggested that the gamblers would be released if they agreed to give him and two other officers some money.
One of the gamblers told his family about the solicitation. His family then informed Loi of the case.
Loi reportedly advised them to have a meeting with Binh. They secretly recorded and filmed the meeting, where the officer received VND60 million (US$2,682).
With the evidence, Loi filed complaints against three officers. The trio was arrested afterwards.
But some members of the gamblers’ families were also arrested after that on charges of “giving bribes.”
Thanh Nien cannot immediately confirm the exact timeline of the arrests.
Local media outlets appeared surprised when Loi was arrested this week.
The man was widely known in his neighborhood as an active whistle-blower. For the last few years, he has collected evidence of corruption by provincial government officials and police.
Thanks to his work, dozens of police officers were disciplined and one was arrested for taking bribes.
Loi had a Facebook page, where he uploaded video clips as evidence.
He wrote on the page: “Fighting corruption is not the responsibility of any single person.”
