Based on the initial recovered fragments, Supiter believes it was a 40mm grenade launched from somewhere using an M-79 grenade launcher, which he said could fire a grenade from as much as 400 meters away.
The police officer said they are still investigating the motive of the incident since they have not received any threat from any group prior to the incident.
But Supiter said a similar incident simultaneously occurred in the municipality of Mlang, also in North Cotabato.
