Provincial police director Superintendent Atanacio Macalan said in a radio interview Thursday that the explosion occurred at around 11 p.m. in a remote area near the private airstrip.
Macalan said their initial investigation showed that the improvised explosive device was made out ammonium nitrate “similar to the type of bomb used in illegal fishing.”
Macalan said they have not yet established the identity of the suspect, but expressed that the motive of the explosion “could be related to the coming local elections.”
“We are not ruling out the possibility that it is election-related,” he said.
