MANILA, Philippines — The Bureau of Corrections (BuCor) has requested the National Bureau of Investigation (NBI) and the Philippine National Police to conduct a parallel investigation into a stabbing incident at the New Bilibid Prison (NBP) in Muntinlupa on Thursday.

The attack resulted in the death of Ricardo Peralta and injuries to Reginal Lacuerta and Bert Cupada.

BuCor officer-in-charge Al Perreras asked NBI Director Jaime Santiago and Philippine National Police chief Gen. Rommel Marbil to conduct independent probes to establish the facts, ensure transparency and identify those accountable in the incident.

Perreras also instructed acting NBP superintendent Roger Boncales to submit an incident report and cooperate fully with the NBI and police investigations.

Those implicated by Espenido have denied his story, which will still have to be validated in court. But in the meantime, the PNP is hurting from his accusations that police received rewards of about P20,000 for every person they killed on suspicion of involvement in illegal drug offenses. Quotas were set for the number of suspects killed, and many innocent people died as a result, Espenido claimed.

At least four prisoners are being investigated for their involvement in the incident.do888
