MANILA- Wally Sombero, an alleged representative of gambling tycoon Jack Lam, has arrived in the Philippines Tuesday morning.

The Philippine Airlines flight carrying the former police officer from Canada arrived at the Ninoy Aquino International Airport (NAIA) before 9 a.m.

Sombero is accused of giving P50-million to two Immigration officials last year in exchange for the release of over 1,000 illegal Chinese workers employed by Lam.

Hours before departing, Sombero agreed to speak with ABS-CBN News' Marieton Pacheco about his upcoming appearance before the Senate Blue Ribbon Committee's probe into the alleged bribery within the Bureau of Immigration on Thursday.

"May mga taong maapektuhan sa gagawin kong pagharap sa Senado... Malungkot ako doon, subalit the people deserve to know the truth," he said.

(There will be people who will be affected when I face the Senate. I'm sad about it, but the people deserve to know the truth.)

Sombero stayed in Vancouver for more than three weeks, skipping previous Senate hearings. His lawyer had said that he was not allowed to board a plane from Canada due to health problems.

Sombero earlier admitted he had planned to file for a refugee claim in Canada because of threats to his life, but family and friends like Senator Manny Pacquiao and journalist Ramon Tulfo convinced him to return to the Philippines to face the inquiry.

"Yes napakaraming threat na dumadating sa'kin, pati [Facebook] ng mga pamilya ko. Alam nila lahat yung tungkol sa'kin. People [are] preventing me from attending the hearing, subalit may katungkulan ako. I cannot abandon the industry," he said.

Sombero also defended the people in the immigration counter when he left the country last January 17.

He said he was only able to secure a clearance to leave because his passport bears the name "Wenceslao" and not "Wally Sombero", which was the name on the immigration lookout bulletin.

He said he did not know then that there would be a Senate hearing.

Sombero also maintained that there was no bribery or extortion that occurred in City of Dreams (COD).

The incident, involving former BI deputy commissioners Al Argosino and Michael Robles, was allegedly caught on CCTV and the footage was shown in the Senate.

"Walang bribery or extortion na nangyari sa COD," said Sombero.

(No bribery or extortion happened in COD.)

He vowed to tell all when he faces the Senate.

"Malaking tanong yan kasi may camera, may pera… People deserve the truth," he said.

(That's a big question because there was a camera and there was money... People deserve the truth.)

Though refusing to give further details, Sombero said he has text messages and other pieces of evidence that would illustrate how his meeting with the BI officials started and how money entered the picture.

Sombero also said high-ranking officials will be named.

Asked if he has a message to Argosino and Robles, he said: "Dapang dapa na yung dalawa, siguro wag na. Kawawa naman. Durog na durog na, kawawa naman. May pamilya rin sila....Mr. Robles, Mr. Argosino pasensya na po kayo; maghaharap harap tayo. You have to stick to your own story."

(The two are already pushed to the ground, I guess I shouldn't. They're pitiful. They're already crushed, it's pitiful. They also have their families. Mr. Robles, Mr. Argosino, I'm sorry; let's face each other. You have to stick to your own story.) With a report by Maan Macapagal, ABS-CBN News
