MANILA, Philippines -- A glaring discrepancy between the time that the captives said they were taken hostage and the time that police were alerted about the hostage-taking was revealed Monday during the resumption of the investigation into the August 23 hostage drama.

Justice Secretary Leila de Lima said that according to the Special Weapons and Tactics team, they received a call about a hostage-taking incident at 9:07 a.m.

However, bus driver Alberto Lubang said the group left Fort Santiago, already under dismissed policeman Rolando Mendoza Mendoza's gun, at 9:45 a.m.

Lubang's testimony was corroborated by those of tourist guide, Diana Chan, and travel agency assistant manager Lourdes Amansec.

De Lima said that an affidavit from the security guards and employees of the building where Mendoza was seen alighting from a car said that the former policeman arrived in the area at 9:30 a.m., dressed in police full battle gear, with a ball cap, a long firearm, and a backpack.

?How can there be a hostage-taking report at 9:07 a.m. if Mendoza only arrived in Fort Santiago at 9:30 am?? a visibly bothered De Lima said.

De Lima said that during an executive session earlier Monday, the SWAT team ?stood by its? statement that they received a call to respond to a hostage-taking incident at 9:07 a.m.

Lubang was grilled for about two hours by the panel before taking a break at 1:40 p.m.

De Lima said they would continue to talk to Lubang during an executive session over lunch.

The hearing has resumed at 2:15 p.m.
