PNP Chief Gen. Debold Sinas (PNP / MANILA BULLETIN) Cadet 1st Class Joab Mar Nacnas warned his three classmates about using liquor inside the PNPA premises after he caught them engaged in a drinking session at the roofdeck of one of the buildings. The confrontation led to a heated argument and ended with Nacnas being beaten up by Cadet 1st Class Denvert Dulansi. Gen. Debold Sinas, chief of the Philippine National Police (PNP), said that he had already ordered the start of the dismissal proceedings against Dulansi and at the same time, ordered the Directorate for Human Resource and Doctrine Development (DHRDD) to place him and two other cadets engaged in a drinking session under restriction.
