MANILA -- The eldest son of Bureau of Corrections chief Nicanor Faeldon was released from detention after prosecutors dismissed the drug charges against him, police confirmed Sunday.

Faeldon's namesake was arrested when police raided an illegel drug den in Naga City last December 14.

The Naga Prosecution Office, in a 7-page resolution dismissing the charges against Faeldon Jr., noted that police officers did not find any narcotics or drug paraphernalia in his possession.

The younger Faeldon earlier tested negative for using shabu and marijuana.

He said it was his girlfriend's father, Russel Lanuzo, who was the subject of the drug raid.

The naga Prosecution Office found probable cause against Lanuzo for possessing shabu and drug paraphernalia in his room, which he claimed were planted by the police.

Faeldon Jr. and his 2 other companions, meanwhile, were released from detention last Friday, said Naga police chief Senior Superintendent Felix Servita.

The Bicol police's legal service division is "still studying the resolution for possible [legal] remedy," he said.

The elder Faeldon earlier said he would not meddle with his son's case, but would "obliterate" him should it be proven that he is a drug user.

The official was criticized during his tenure as chief of the Bureau of Customs after some P6.4 billion worth of shabu slipped through the agency's port inspections. -- Report from Jessa Mylce Mella, ABS-CBN News
