Police operatives have arrested two of 11 suspects in the seajacking incident in waters off Siromon Island, Zamboanga City that left eight fishermen dead.

Seven men survived the seajacking incident on Monday as five men jumped overboard and swam to a nearby island, while two others who remained on the boat were unharmed, Philippine Coast Guard officials said.

Arsani Samlani, a local fisherman, was invited to the police station Wednesday after a survivor positively identified him as one of the culprits, officials said.

Another suspect identified as Mizfar Nuno alias Ravin Atain was nabbed earlier this week during a buy-bust operation in Seaside Sangali.

Multiple murder raps have been filed against Samlani while cases of multiple murder and illegal possession of explosives and illegal drugs were filed against Nuno.
