MANILA, Philippines -- The Department of Justice (DoJ) intends to test the credibility of national broadband network (NBN) witness Rodolfo Noel Lozada Jr.

The DoJ panel investigating the NBN scandal will order Lozada to identify personnel of the Police Security Protection Office (PSPO) who allegedly abducted him at the Ninoy Aquino International Airport (NAIA) in February.

During the preliminary investigation on Thursday of the kidnapping and attempted murder charges Lozada filed against his alleged abductors, the panel chaired by Senior State Prosecutor Emily Fe Delos Santos refused the request of Lozada's counsel Edwin Lacierda to provide them with photos of PSPO personnel to properly identify those who supposedly seized him from the airport last February.

Delos Santos agreed with lawyer Felizberto Verano that the right against self-incrimination of the respondents from the PSPO would be violated if they provided Lozada with the pictures of the policemen who submitted their counter-affidavits to the DoJ Thursday.

"The testing of the credibility of the complainant rests upon the panel?We will do the same method we do in other kidnapping cases," Delos Santos said.

She told Verano to provide Lozada with pictures of all PSPO personnel who were on duty during his alleged abduction so that Lozada can pinpoint those that are involved.

PSPO director Senior Superintended Romeo Hilomen said there were about 1,000 PSPO personnel on the active list that month.

"You give them all the pictures of those 1,000 and let him identify" the alleged abductors, Delos Santos said.

The preliminary investigation was the first time that Lozada came face to face with Aviation Security Group personnel Rodolfo Valeroso, who subscribed his counter affidavit.

Lozada also submitted closed circuit TV footage of his arrival at the Ninoy Aquino International Airport (NAIA).

The panel gave Philippine National Police Director General Avelino Razon Jr. and NAIA Assistant General Manager up to April 8 to submit their counter-affidavits, and Lozada's camp 10 days to submit a reply.

The panel is yet to schedule a clarificatory hearing.

The other respondents to the charges filed by Lozada are Environment Secretary Jose Atienza, NAIA assistant general manager Angel Atutubo, Aviation Security Group officer Rogelio "Roger" Valeroso, a certain "Jaime," the designated driver of the vehicle in which Lozada was supposedly spirited and driven as far as Laguna, and several John Does.
