Personnel from the Criminal Investigation and Detection Group (CIDG) have served a subpoena against Sen. Ronald "Bato" dela Rosa at his residence in Davao.

The move by the Philippine National Police (PNP) followed the order issued yesterday by Department of the Interior and Local Government (DILG) Secretary Jonvic Remulla to reopen the investigation into the extrajudicial killings that took place in Davao.

CIDG personnel were unable to locate Sen. Dela Rosa when they served the subpoena at his Davao home, as well as at his office at the Senate in Pasay City.

According to PNP Public Information Office Chief PBGen. Randulf Tuaño, only the caretaker of Bato's residence received the subpoena.

The subpoena, signed by CIDG Director PMGen. Robert Morico II, orders Sen. Dela Rosa to appear before the Major Crimes Investigation Unit (MCIU) of the CIDG at Camp Crame on Thursday, May 14, at 10 AM.

He is being required to submit a sworn affidavit and supporting documents, and to provide information related to the alleged extrajudicial killings that occurred while he was serving as City Director and Regional Director in Davao.

Should he fail to comply, Dela Rosa may face indirect contempt.

In May 10, DILG Secretary Jonvic Remulla directed the PNP to reopen the investigation into the war on drugs. He said around 100 cases of extrajudicial killings were recorded during Sen. Bato's assignment in the Davao Region.

The Secretary also clarified that the document be served is not an arrest warrant from the International Criminal Court and that there are no plans to arrest Dela Rosa.
