MANILA, Philippines -- Authorities awarded P500,000 to an informant who led them to neutralize a suspected Abu Sayyaf explosives expert in Quezon City in November 2007.

The informant, who wore a leather jacket and a black ski mask over his face, received the cash from Director Geary Barias, chief of the National Capital Region Police Office (NCRPO), and Major General Fernando Mesa, commander of the military's National Capital Region Command (NCRCom), in Camp Aguinaldo on Monday.

The suspect, Alpaker Said, alias Abu Jandal, was killed in a shootout after authorities swooped down on a bandit lair in the Payatas district last November 16.

Said, an alleged Abu Sayyaf explosives expert, was reportedly involved in the November 13 bomb attack on the House of Representatives that killed Basilan Representative Wahab Akbar and five other persons, Barias said.

Several others, including two solons, were wounded.

Former Basilan representative Gerry Salapuddin, Akbar’s political rival, and several others have been charged for the bombing.

Said also had a standing warrant for kidnapping and serious illegal detention, Barias said.

"He [tipster] led us to the hideout of [Said’s] group," Mesa said, without elaborating on the informant's identity due to security reasons.

Asked what Said's role in the November 13 attack was, Barias said: "We can only at this time speculate if he provided technology to the group or if he rigged the bomb himself."
