Three students were killed and 20 others were wounded when the two suspects, aged 14 and 15 and armed with a handgun each, opened fire Monday at the San Jose National High School in central Tacloban City.

The Cybercrime Investigation and Coordinating Center said its decision to block Gorebox was prompted by an ongoing police investigation which showed that one suspect was an avid user of the app, adding that this will allow authorities to determine "whether the platform played any role in the actions of the suspects."

The decision would be enforced starting Tuesday, undersecretary Aboy Paraiso of the cybercrime center said in a statement.

"We cannot ignore possible online influences that may have contributed to this tragic incident," Paraiso said, without specifying how long the app will be blocked.
