MANILA (UPDATED) - President Rodrigo Duterte on Thursday slammed Cebu City Mayor Tomas Osmeña for allegedly being arrogant.

In a speech in Mandaue City, Cebu, Duterte accused Osmeña of suffering from “hubris” and allegedly treating Cebu City as his personal property.

“Itong pinagmamayabang nito, matagal na sa politika na kung makapagsalita na ‘huwag galawin ang Cebu kasi amin ‘to.’ P****g i*a mo, g**o ka pala. Gusto mong lumabas sa Pilipinas? Eh di bitbitin mo 'tong Cebu dun sa Pacific, alis dito,” Duterte said in Cebuano in a speech in Mandaue City, Cebu.

“Huwag mo akong loko-lokohin ha? Kasi hindi ako Cebuano na pwede mong tapak-tapakan… Kung makapag salita akala mo kung sino, ‘Huwag pakialaman ang Cebu kasi kaya namin ‘to.’ Who are you to say that? It’s as if you own Cebu. By what right? Just because you were a former president’s son or grandson?”

Duterte said he would slap Osmeña for supposedly accusing him of being a protector of the illegal drug trade.

Aside from hitting the outspoken Cebu City mayor, Duterte also mentioned his other critics such as Senator Antonio Trillanes IV, communist leader Jose Maria Sison, and lawyer Elly Pamatong, who has filed a quo warranto petition against the President.

“Bakit pumasa ito (Pamatong) ng UP? At ito ding si Trillanes ba't nakalusot sa PMA? Ako sigurado ako na ang IQ ni Pamatong hindi aabut sa 14. Pero sa milagro milagro, nakapasa ng UP ha? Si Trillanes mga 16 yan... itong si Tomas ewan kung ilan,” he claimed.

Osmeña’s rift with Duterte’s presidential adviser on the Visayas, Michael Lloyd Dino, is public knowledge. The two have reportedly been at odds over the Bus Rapid Transit project in Cebu City which the mayor wanted to proceed but Dino allegedly blocked. The government has shelved the project.

Osmeña was also not invited to the meeting of local chief executives in Cebu last May, along with Ronda Mayor Mariano Blanco, and Daanbantayan Mayor Vicente Loot, the Freeman reported.

Osmeña, in a statement, said the President is "entitled to say whatever he wants.

"As a lawyer, I am sure that he knows there are two sides to any story, and not just what Dino and PRO-7 are telling him. The first step in solving a problem is to admit there is a problem, and if the police refuse to admit there is a problem because 'Cebu is still safe,' then they are only making it worse," he said.

"If I have to be the bad guy for mentioning that there is a problem, so be it. No problem, this is what I signed up for."

Osmeña had also locked horns with then Justice Secretary Vitaliano Aguirre after the latter accused him of being a protector of drug lords in the city.

He denied the allegation and challenged Aguirre to file a case against him.

Osmeña initially sought Aguirre's disbarment as he alleged the former secretary intervened in the complaint the mayor filed against 2 branches of BDO Unibank in his city, which allegedly did not pay correct taxes. The Department of Justice had dismissed the complaint for insufficiency of evidence.

Osmeña has also lamented the recent extrajudicial killings in his city, saying policemen were involved in them.

He claimed that the killings spiked in the city after Cebu City police chief Senior Superintendent Royina Garma and Central Visayas regional police director Chief Superintendent Debold Sinas came to power.
