Sarah Discaya surrendered to the National Bureau of Investigation (NBI) on Tuesday after President Ferdinand "Bongbong" Marcos Jr. announced that an arrest warrant is set to be issued against her in connection with the floodgate case.

Contractor Discaya and her lawyer showed up at the NBI headquarters around 10 a.m.

Marcos, in a video message, said a warrant for the arrest of Discaya is expected this week.

Sarah and her husband Pacifico “Curlee” Discaya are in hot water after their construction firms were tagged in anomalies in the country’s flood control projects.

The couple own the Alpha and Omega General Contractor & Development Corporation, one of the 15 companies named by Marcos that secured 20% of the flood control projects in the country.

The President also said there were eight personnel of the Department of Public Works and Highways in Davao Occidental who sent letters expressing their intention to surrender before the NBI to face cases related to the flood control anomalies.

Discaya and nine others are facing cases for alleged malversation of public funds and alleged violation of Section 3(e) of Republic Act No. 3019, or the Anti-Graft and Corrupt Practices Act, in connection with the P96.5-million ghost flood control project in Barangay Culaman in Jose Abad Santos town in Davao Occidental.

Earlier, the couple expressed intent to become state witnesses in the probe, but the Office of the Ombudsman said they have zero chance of being one because of their deep involvement in the anomalies.

Authorities also revealed the couple stopped coordinating with the Department of Justice.
