MANILA - The National Bureau of Investigation (NBI) will use a lie detector test on those involved in the alleged anomalous P74-million printing job contract done by the National Printing Office (NPO) for the Social Security System (SSS).

NBI-Anti Fraud Division head Atty. Irvin Garcia said they will use all possible means to uncover the truth behind the said transaction, including the use of a lie detector test on the accused.

"All means of investigation shall be done to make sure we get to the bottom of this," he said.

The NPO had a P74-million contract with Western Visayas Printing Corp. but awarded the work orders to three other firms.

Best Forms Security Printer, owned by Benjamin Yam; Tri-Print Work of Ramil Tamayo; and Metro Color Co. of Celso Viray have responded to the NBI’s summon.

NPO Director Francisco Vales and former bids and awards committee chairman Sherwin Prose Castaneda were also present during the first investigation day of the NBI.

It was revealed during the investigation that all present submitted documents regarding the controversial contract.

Garcia assured that the NBI will file charges against those who will be found liable.

Records show the contract was first awarded to Western Visayas Printing, owned by Raymond Malapayo.

The alleged NPO-SSS scam was earlier investigated by Presidential Communications Operations Office's legal affairs office as directed by Secretary Martin Andanar.

Members of the NPO bids and awards committee resigned following the investigation.

Undersecretary for Legal Affairs Atty. Enrique Tandan III then referred the matter to the NBI for further investigation.
