A lawmaker in the Philippines has started digging into the alleged attempt of the country’s “No.1 gambler” to bribe chief of the Philippine Charity Sweepstakes Office (PCSO).

On Tuesday, PCSO General Manager Alexander Balutan said government gambling consultant Charlie “Atong” Ang dangled a monthly bribe of PHP200 million ($3.87 million) in September 2016 in exchange for the full control of the country’s Small Town Lottery operations.

To shed light on his claim, The Philippine Daily Inquirer reported that Senator Panfilo Lacson has summoned Balutan to the next legislative hearing on STL operations.

Lacson pointed out that Balutan first mentioned the PHP200 million (US$3.87 million) as an estimated government earning if it took over the STL operations nationwide and not as a bribe during the January 24 hearing.
