Former narco-politics "whistleblower" Peter "Bikoy" Advincula was held by police on Friday in connection with the killing of three people in Daraga, Albay.
Police identified the victims as Donsol Councilor Helen Advincula Garay, 53, and businessmen Karren Averilla, 44, and Xavier Mirasol, 61.
The victims were found dead inside an ukay-ukay shop allegedly owned by Advincula in Barangay Busay, Daraga.
"Allegedly, there was an invitation made by Bikoy to the aspiring vice mayor of Donsol, Sorsogon — Helen Garay. The invitation was allegedly for a meeting with a candidate in Daraga," said Lt. Col. Bogard Arao, chief of the Daraga Municipal Police Station said.
Garay, he said, decided to invite three others, including Averilla and Mirasol who are both running for councilor of Donsol in next year's elections.
The third person, Lalaine Herrera Amor, did not attend the meeting.
Police said Amor, accompanied by her husband, went to their station around 11 p.m. to report that her three companions were missing.
Based on her statement, Advincula fetched her and the three other victims one by one in a blue Toyota Vios.
Amor got suspicious because it was already late in the evening and she refused.
Advincula earlier tagged the family of President Rodrigo Duterte in the illegal drug war trade.
