MANILA - Senator Antonio Trillanes IV on Tuesday visited banking institutions in Singapore in a bid to reject President Rodrigo Duterte's allegation that he maintained secret bank accounts.

Duterte recently accused Trillanes of keeping bank deposits "all over" Singapore, China, Hong Kong, Australia and America. Photos then circulated online supposedly showing several $50 remittances to the senator's alleged accounts.

Trillanes went to the DBS branch in Singapore's Alexandra Road with a printout of a supposed account registered under his father's name.

A DBS teller however said there was no such account at their bank.

Trillanes tried but failed to get a certification from DBS because he was not a client.

The opposition lawmaker then went to the Raffles City Tower to check business listings for the "Hongkong Shanghai Bank," where he also allegedly concealed account with a balance of some SGD 278,000.

He found no listing for the supposed bank.

Trillanes last week signed a waiver for 12 bank accounts being linked to him, and dared Duterte to do the same.

The senator claimed Duterte only accused him of amassing hidden wealth to divert public attention following his allegations that the President's son, Davao City Vice Mayor Paolo Duterte, is part of a syndicate that allegedly smuggled P6.4 billion worth of shabu into the country last May.

The senator also linked the vice mayor and his brother-in-law, lawyer Mans Carpio, to the so-called "Davao Group," which allegedly accepted bribes in exchange for the release of questionable shipments.

Duterte and Carpio have repeatedly denied the allegations and even faced a Senate inquiry.

During last year's campaign, Trillanes claimed that the President, then mayor of Davao, failed to declare P211 million in 17 accounts.
