MANILA - The Philippine National Police on Monday said it is still checking President Rodrigo Duterte's allegation that his critics are planning to remove him from office.

Duterte over the weekend said the Liberal Party, communist rebels and Senator Antonio Trillanes IV were in cahoots over the alleged ouster plot that will "go into high gear" in October.

"We are looking into all this information. These are all serious allegations. Hindi natin puwedeng palampasin ito (we cannot brush this off)," PNP chief Director General Oscar Albayalde told reporters.

"The President has unlimited source of information, hindi lang (not only the) PNP. Whatever he says, we take them seriously," he added.

Trillanes, whom Duterte stripped of amnesty from leading 2 failed mutinies, denied any hand in the alleged destabilization move.

"Wala akong nire-recruit, walang ouster all right. I don't expect them to take my word for it. They can validate it all they want," he said in a press briefing.

(I am not recruiting anyone, there is ouster plan.)

LP President Kiko Pangilinan has echoed Trillanes' denial, urging the President to instead address problems like rising consumer prices.
