Three suspected members of the outlawed Bangsamoro Islamic Freedom Fighters (BIFF) were arrested by police authorities here on Sunday night.
Inspector Harris Lino, Shariff Aguak police chief, said the trio were on board a motorbike speeding in Barangay Poblacion Mother when lawmen intercepted them.
One of the three suspects tried to pull a hand gun but was subdued by lawmen at 10 p.m.
A body inspection resulted in the confiscation of three hand grenades, three cal. 45 pistol, several magazines for M-16 Armalite rifle and unregistered motorcycle.
"We are determining if they are members of the BIFF which is on the run due to military operation," Insp. Lino said.
He identified the suspects as Omar Sawal, Rashid Ayungan and John Yunaw, all residents of Shariff Aguak.
"They could not explain why they carry high powered guns while a military operation against BIFF was on-going," he said. "We can only surmise they were BIFF members."
"They will be charged for illegal possession of firearms and explosives," Lino said of the suspects who are now detained at PNP-Shariff Aguak lock up cell.
