MANILA -- The source of the bomb threat at Ateneo de Manila University (ADMU) has been traced by police, Quezon City Mayor Herbert Baustista said Wednesday.
In an interview with ANC, Baustista said messages were sent through SMS by someone in Marikina City.
Investigators went to Marikina, but were unable to immediately identify the person who sent the text messages.
The source is still being tracked down by the police.
ADMU suspended work and classes on Wednesday morning due to the bomb threat.
The university supposedly received three text messages regarding the bomb threat beginning 9:20 a.m.
Aside from the tertiary colleges, ADMU's Katipunan campus also includes the primary and secondary levels.
A thorough search of the campus produced no bomb.
The school campus reopened at 5 p.m. Wednesday for those who wanted to retrieve their belongings.
Classes will resume Thursday.
Bautista praised the university's response to the threat. He said the institution peacefully and safely managed the situation.
He added that other schools should also be trained on how to respond to such threats.
"Madalas kasi mga fire drill, earthquake drill. Pero paano ang gagawin kung may bomba, may barilan, katulad sa Columbine. Kailangan din natin ma-train ang mga eskwelahan sa ganitong mga sitwasyon," he said.
