MANILA - Sen. Vicente Sotto III said the public should expect an “explosive” revelation in the Senate’s probe on the police force’s alleged recycling of illegal drugs.

The Senate Blue Ribbon and justice committees will resume its probe on Wednesday, and Sotto said the panels have gathered new evidence and witnesses.

“I don’t know if I’m at liberty to tell you but there is really something explosive again. There is I think new evidence, one or two new witnesses, because I signed nine subpoenas last night,” Sotto said in a forum in Manila.

The Senate panels initially tackled the alleged anomalies at the Bureau of Corrections, but the inquiry has since went on to probe the alleged recycling of seized illegal drugs by so-called “ninja cops.”

The inquiry has revealed that Philippine National Police chief Gen. Oscar Albayalde supposedly attempted to block the dismissal of his former subordinates at the Pampanga police office who were accused of making off with millions worth of meth seized during a 2013 drug raid.

The revelation prompted calls for Albayalde to step down ahead of his Nov. 8 retirement. Albayalde said he won’t step down.

President Rodrigo Duterte, however, said he wants “clear proof” that would directly link Albayalde to the alleged errant cops’ illegal activity.
