MANILA, Philippines -- Manila Mayor Alfredo Lim said Saturday he was not going to lift a finger in defense of his son Manny, who was arrested along with two other people on a drug charge the previous night.

"If he violated the law, let the ax fall where it may. Ang tinutulungan ko lang yung mga naagrabyado. ?Yan naman ang pinaglalaban ko. (I just help those who are aggrieved. That?s what I?m fighting for.),? Lim said in a phone interview.

?The law applies to all. He's 44 years old, he should be ready to face the consequences of his actions," Lim said.

The mayor admitted that he and his son have not been on speaking terms for the past few months now. He added that he received a call from Philippine Drug Enforcement Agency chief Dionisio Santiago informing him about his son?s arrest.

"I told him (Santiago), 'Congratulations to your men,'" Lim said.

Details were not immediately available from PDEA.

A dzBB radio report said Manny Lim, a businessman, was arrested during a buy-bust operation in Binondo Friday night.

The report said Lim was arrested along with two others in a hotel on Tomas Mapua Street by PDEA operatives.

Reportedly seized from them were 100 grams of metamphetamine hydrochloride or shabu worth P600,000.

The mayor is a former city police chief known as "Dirty Harry" of the Philippines for his ruthless crackdown against crime.
