MANILA (Mabuhay) – Some policemen were behind the ambush-slay of Chief Inspector Roderick Medrano, a spokesman for the Philippine National Police said.

Chief Superintendent Reuben Theodore Sindac made this disclosure and announced the arrest of four suspects whom he identified as Clemente Bersoza, Larry Consolacion, Joeam Marco, and Rodener Necesito.

The arrests came a day after the Quezon City police formed an investigating team to hunt down the killers.

In a separate text message earlier in the day, Sindac said the four suspects were arrested by the operatives of the Special

Investigation Task Group (SITG) Medrano around 3 a.m. ‎of Wednesday.

Medrano,41, was the head of the operations section of the Quezon City Police District (QCPD) Station 4 in Novaliches, Quezon City.

He was killed in an ambush on Monday along San Diego Drive in Barangay (village) Kaligayahan, the boundary of Fairview and Novaliches, as he was driving his two sons to school.

Immediately after the killing, Chief Superintendent Richard Albano, QCPD chief, ordered on Tuesday the creation of SITG Medrano to track down the attackers.

Senior Superintendent Procopio Lipana, QCPD deputy district director for operations‎, was tapped by Albano to head the task group.

Three .45 caliber pistols, an M30 carbine, .38 caliber revolver, a hand grenade and a white Toyota FX without plate number have been confiscated from the alleged perpetrators.

The arrested individuals are now under the custody of the Criminal Investigation and Detection Unit (CIDU) of the QCPD for documentation.

Medrano’s fellow policemen described him as “a humble person with no known enemies.” (MNS)
