MANILA—Foreign Affairs Secretary Teodoro Locsin Jr. on Saturday vowed that his department will get to the bottom of the issue involving a foreign company running away with Filipinos' passport data.

Locsin earlier revealed that a passport production contractor, whose services the government had terminated, allegedly "made off" with the data.

He then took to Twitter to answer questions about the development, as he offered blistering takes on the incident.

The problem started under GMA’s DFA and got worse under PNoy’s DFA. IT WILL BE SOLVED BY PRRD’s DFA under licsin. The yellow crowd who perpetrated the passport fraud are in a panic because we are gonna autopsy their crooked deal. Period.

I just want it fixed and not repeated. Redundancy of data was promised by previous contractor but not fulfilled or just denied us. We have no knowledge whatsoever if it has been corrected. Like a cuckolded husband, we are always the last to know. https://t.co/fZtbv5rkKI

The National Privacy Commission has said it would investigate.

Senate Minority Leader Franklin Drilon said charges should be filed against the company, while Senator Risa Hontiveros said the government "owes the entire country an explanation" over the stolen data.
