Metro Manila (CNN Philippines, August 20) — New Bilibid Prison (NBP) inmate Michael Cataroja, who went missing and was rearrested, showed how he escaped from the maximum security compound by riding a garbage truck.

In videos shared by the Bureau of Corrections (BuCor) on Sunday, Cataroja demonstrated to the members of the board of inquiry created by Director General Gregorio Catapang Jr. how he clung to the bottom of the truck to escape from the NBP.

Cataroja was reported missing on July 15 and was rearrested in Rizal earlier this month. He has been turned over to NBP's maximum security compound, the BuCor said.

LtGen Rhoderick Armamento, commander of the PNP Area Police Command-Southern Luzon, said Cataroja was able to pass through security after copying NBP's visitor stamp on his arm using a ballpen.

The Senate Committee on Justice and Human Rights investigating the reported "mass grave" in the NBP will now focus on NBP's security after the rearrest of Cataroja.
