(UPDATED) Philippine National Police (PNP) chief Ronald "Bato" Dela Rosa on Friday cried foul after being criticized for attending a concert amid the controversy on the kidnapping and killing of a South Korean businessman inside Camp Crame.

Dela Rosa was spotted at the front rows of the Bryan Adams concert on Thursday night.

The PNP chief said skipping the concert will not help solve the case of Ick-joo Jee, who was kidnapped and killed allegedly by police officers.

“Matagal nang patay ang biktima noong nanood ako ng concert. Mabuhay ba ang Koreano kung hindi ako manood (The victim was when I attended the concert. Will he rise from the dead if I decided not to go)?” he said.

Dela Rosa issued the statement in an ambush interview on the sidelines of the premiere night of a movie at a mall at the Bonifacio Global City.

Just hours before the concert on Thursday, Dela Rosa confirmed that Jee, who went missing in October 2016, was killed killed near the PNP community relations group office.

Calls for his resignation later circulated on social media.

Dela Rosa said he is willing to give up his post if President Rodrigo Duterte asks for it. “Kung papayag presidente, then maghintay lang. Bababa ako.”

House Speaker Pantaleon Alvarez on Friday said the PNP chief should vacate the post to spare the president from further embarrassment.

To this, Dela Rosa commented: “(A)no pa ang gusto nilang gawin ko? Mag-hara kiri ako? Magpapakamatay ako para masaya sila. Pero masakit iyong hara kiri. Kung makipagsabayan siya sa akin puwede siguro, iyong nagsabi na gusto akong mag-retire, sabay tayo, mag-hara kiri tayo.”

(What more do they want me to do? For me to commit hara kiri? I would take my own like to make them happy. But hara kiri would hurt. Maybe if he goes with me, those who said I should retire, let's do it together.)

He, however, added that what’s important is that the case is rolling. “Na-solve naman ang kaso. Nahuli na iyong mastermind. Identified na iyong iba na hindi pa nahuli at pinaghahanap na natin (The case has been solved. The mastermind has been identified and we are looking for the other suspects),” he said.

Dela Rosa said the controversy rocking the PNP won’t get in the way of his fight against illegal drugs.

“These are all distractions sa ating war on drugs. Mayroon pa akong trabaho na gagawin. Kaya mahaba pa trabaho natin dito. Malayo pa ang ating pinupuntirya.”

(These are all distractions from our war on drugs. I still have a lot of job to do. We are still a long way from our goals.)

Ask what he wishes for his birthday on January 21, he said: “Sana bumait na lahat ng pulis, wala nang pulis na sindikato (I hope all policemen will be good, no police would be involved in syndicates anymore).”
