Operatives of the Caloocan City Police are still trying to determine whether the 300 kilograms of explosives recovered by the Special Weapons and Tactics team in the city over the weekend were intended for creating disturbances in northern Metro Manila.

Senior Supt. Jude Santos, Caloocan City police chief, said the explosives were recovered by chance when SWAT operatives noticed an unattended baggage at the corner of B. Serrano Street and 7th Ave. in Grace Park last Saturday.

When they checked, the operatives were surprised to discover two packaging boxes and four woven plastic bags of ammonium nitrate, a kind of fertilizer used as ingredient in making bombs weighing more or less 300 kilograms. They also found two blasting caps inside the bag.

Santos said the recovered materials were immediately secured and turned over to the PNP Crime Laboratory.

At least three explosions rocked two banks in Caloocan and Valenzuela City in the past month using the same type of explosives.
