FIRE broke out at the Caloocan Police Headquarters early Tuesday but was quickly put under control, an official said.
PO3 Rafael Abuan Jr., chief of Supply and Logistics, said structural damage was estimated at P1 million.
Abuan said he heard an explosion from the Northern Media Group Headquarters.
He said the proximity of the headquarters to the office of the Scene of the Crime Operatives (SOCO), which housed ammunition recovered from past cases, caused the fire to spread quickly.
The cause of the explosion is still unknown, although authorities said the incident was most likely an accident.
No casualties were reported and all prisoners were safe and accounted for. MARTINA MENDOZA
