MANILA (2nd UPDATE) -- Peter Joemel Advincula, who introduced himself as "Bikoy", a hooded figure who linked President Rodrigo Duterte's family to the narcotics trade in several viral videos, said Thursday that his allegations were "all lies".

Advincula also said his claims were "orchestrated" by Sen. Antonio Trillanes IV and the Liberal Party, a claim immediately denied by an official official of the group and an ally of the lawmaker.

"Lahat ng nangyari sa Ang Totoong Narco-list, video episode 1 to video episode 5... lahat iyun pawang scripted, lahat iyun pawang kasinungalingan," Advincula told reporters.

(Everything that happened in the Ang Totoong Narco-list, from video episodes 1 to 5, these were all scripted, they were all lies.)

"Walang katotohanan lahat-lahat iyun at iyun ay pawang orchestrated lang ng mga nasa kabilang party, which is Liberal Party under the handling of Senator Sonny Trillanes IV," he added.

(There is no truth to all that and it was orchestrated by the opposing party, which is the Liberal Party under the handling of Senator Sonny Trillanes IV.)

LP president for external affairs Erin Tañada, rejected Advincula's claims.

"It is easy to say that it is the LP. The LP has denied that it knows Advincula. Advincula should provide the evidence to prove his allegation," he said.

Trillanes has also denied accusations that he is behind the viral videos that supposedly link Duterte to the illegal drug trade.

Trillanes earlier congratulated the people behind the videos that allegedly linked the Duterte family to illegal drugs. "Having said that, I really wish I was part of the making of the videos so I could relish these moments but sadly I am not," he said.

"Anu't ano pa man, hindi talaga natutulog ang Diyos," he added.

Bikoy, in the "Totoong Narco-list" videos claimed drug money was funneled into the bank accounts of Duterte's son former Davao City Vice Mayor Paolo Duterte, his son-in-law Atty. Manases Carpio, and former aide Christopher Go.

Advincula claimed he met Trillanes through a priest. He also linked two more opposition senators to the alleged plot to discredit the administration.

The plan dubbed "Project Sodoma", he said, aimed to oust Duterte and put in power Vice President Leni Robredo, chairperson of LP, before June 30, 2019.

In exchange for appearing in the viral videos, Advincula claimed he was promised money, a government post and absolute pardon.

He said he was promised 500,000 pesos to appear in the videos, but the money did not come through.

He said Trillanes allegedly stopped contacting him after the May 13 elections, after opposition candidates failed to win a Senate seat.

"Hindi ko po kayang panindigan iyung mga scripted lang na kuwento na ngayong talo na ang mga kandidato nila, nararamdaman ko na unti-unti na akong nilalaglag at kinatatakutan kong baka sila pa ang mag-eliminate sa akin kinalaunan dahil wala na akong silbi," he said.

(I can't stand by my scripted stories. Now that their candidates have lost, I feel that they are slowly letting me take the fall and I fear that they will eliminate me eventually because I am already useless.)

Trillanes' ally, outgoing Magdalo Party-list Rep. Gary Alejano, said he will consult other Otso Diretso candidates on possible charges against Advincula for his allegations.

Advincula turned himself in to the Northern Police District on Wednesday and was turned over to the Philippine National Police headquarters at Camp Crame.

PNP chief General Oscar Albayalde denied police coached Advincula in retracting his earlier claims.

Senate President Vicente "Tito" Sotto earlier cast doubt on the credibility of Advincula, saying the latter had also tried in 2016 to link officials of the then outgoing Aquino administration to the illegal drug trade.

Advincula said Corrections officials who were angry at then justice secretary Leila de Lima were behind his claims against the Aquino administration.

Advincula will be brought to Baguio, where he has a standing warrant of arrest for estafa and large-scale illegal recruitment, said Albayalde.
