The accused lawmakers are Senators Ramon Revilla Jr., former Senate president Juan Ponce Enrile and former Senate President Pro-Tempore Jinggoy Estrada.
The Department of Justice and the National Bureau of Investigation submitted the complaint around 3:30 p.m on Monday.
The pork barrel scam was allegedly led by Napoles, who turned fugitive after a court ordered her arrest over serious illegal detention of her employee and main scam whistleblower Benhur Luy. She surrendered two weeks later.
Napoles was accused of being behind questionable NGOs that implemented ghost projects using pork funds, also known as the Priority Development Assistance Fund.
The funds were supposedly siphoned to the pockets of Napoles and lawmakers. Luy in a Senate hearing said the division could reach up to 50-50.
Napoles is detained at Fort Santo Domingo in Laguna. —KG, GMA News
