MANILA (UPDATED) - The National Capital Region Police Office (NCRPO) clarified that a memorandum from the intelligence unit of the Valenzuela police circulating on social media is authentic.

But NCRPO Director Oscar Albayalde on Tuesday stressed that the information in the memo about an alleged plot to bomb several areas in Metro Manila has not been verified.

"The memorandum, actually, is authentic but the information is meant for validation. The memorandum is signed by the chief of the intelligence division of Valenzuela," he told ANC.

Albayalde said the memo does not say the alleged bomb plot is bound to happen, given that the information is still being checked with police community precincts up to the regional level.

"It's not meant to scare the public. It's not meant to tell that this will actually be conducted during this time and this date," he said.

"Once you get the information, you have to validate it... Once it's validated, you have to share it to all territorial units so there will be no failure of intelligence on your part," he said.

Albayalde said the leaked memo circulating on social media should've been marked as confidential.

He earlier said he ordered the Northern Police District to investigate the information contained in the document.

"We assure the public that we do not take for granted any information reported to us. We process every information received and the task of our police on the ground is to validate all these," he said.

Albayalde urged the public to stop sharing unverified information that may cause undue alarm.

"We also express our gratitude to concerned individuals & our friends from the media who were the first inform us about the document. This is vigilance in action," Albayalde added.

The police memo dated June 16 refers to a supposed bomb plot by Maute terrorists targeting certain areas in Quiapo, Manila, Quezon City and Makati.
