No one was injured in the incident.
The fire started in the house of a certain Arnel Omigan at around 1:06 a.m.

A total of 13 firetrucks were sent to the scene to help put out the blaze, which reached the third alarm. The fire was contained around 2:56 a.m.
Consignado said their initial investigation showed that faulty electrical wiring could have caused the fire. Rhodina Villanueva
