Hours before the October 21 blast, police in Manila captured a man they said was a senior member of the Muslim extremist group, Abu Sayyaf, suspected of staging the earlier blasts. Police arrested five more suspects on the 22nd. On November 15, Abdulmukim Edris, who had a million peso bounty on his head, was arrested in Pasay after the issuing of 11 warrants of arrest by the regional trial court in Isabela, Basilan for a string of pending criminal cases, including murder and kidnapping for ransom. Edris was tagged as the mastermind in the October 17 bombings.
