were motivated by a "grudge" over bullying. One was arrested soon after the shooting at the San Jose National High School in Tacloban city while the second later surrendered. The suspects were armed with a .38 revolver and a 9mm pistol, the latter of which belongs to a policewoman who is one of the suspect's relatives and is now in custody. Gun violence is not uncommon in the Philippines, but school shootings are extremely rare.  "Red flags" in the teens' behaviour had been missed and with them the opportunity to prevent the crime, the national police spokesperson told reporters on Monday. "The two [suspects] went straight to the classroom. Without saying anything, they started firing", Colonel Allen Rae Co told reporters. "Initially, it appears that the motive of the crime is grudge for school bullying." He said it was unclear at this stage of the investigation whether the intended targets were in that classroom. “About 40 empty shells have been recovered from the crime scene”, Co said. Along with the three people who died, three were injured by gunshots, and four were wounded in their "panic" to get away, he added. Investigators have found violent videos of one of the teens firing a gun on his social media, Co alleged. (BBC)
