(UPDATE) A relative of President Rodrigo Duterte was flagged down by authorities for using an invalid US driver's license in Davao City, a Land Transportation Office (LTO) official said Friday.

Assistant Regional Director Neil Cañedo of LTO-Davao Region said Nuelle Duterte, the President's niece, was also using a commemorative plate bearing Duterte's image.

A US driver's license can only be used in the Philippines for 90 days. But Nuelle arrived in the country on August 14, using up all of the license's 90-day privileges, said Cañedo.

Cañedo said he let Nuelle go but warned her will she will be given a ticket if she will not change her vehicle's plates.

Nuelle is known for being a critic of his uncle's administration. She supported Chel Diokno, an opposition candidate, during the 2019 senatorial elections.

Presidential spokesman Salvador Panelo said the incident was not an issue.

"It only shows that in the Duterte administration, whether nationally or locally, particularly in Davao, laws are enforced against violators no matter who they are," Panelo told ABS-CBN News.

ABS-CBN News sought comment from Nuelle but she has yet to respond, as of this writing.
