MANILA - The Philippine Charity Sweepstakes Office (PCSO) is open to investigation amid allegations of corruption in the agency, its chief said Wednesday.

This, as PCSO resumed lotto operations several days after President Rodrigo Duterte ordered the agency's gaming schemes to stop due to "massive corruption."

"Corruption, napakalawak po ng definition (has a wide range of definition). I will leave that to the investigators. Ang parameters ko (My parameters are) I was able to achieve my goals. Our office is open sa lahat ng klase ng investigation (to all kinds of investigation)," PCSO General Manager Royina Garma told reporters.

"While investigators are validating the report, ako po ay gagawa din ng trabaho na alamin paano i-improve ang proseso ng games namin para maging more transparent (I will do my job to improve the process of our games to be more transparent)."

The justice department earlier ordered the National Bureau of Investigation to look into alleged graft and corrupt practices at the PCSO.
