The suspects are Afekhana Esther, Comfort Muoneke, and Segun Osaimokhai.
According to a statement issued on Sunday by the anti-graft agency, Esther, one of the suspects, was apprehended in Benin City's Ward 1 at St. Patrick's Catholic Church with 20 PVCs belonging to various individuals.
According to the EFCC, the suspect claimed that Muoneke and Osaimokhai gave her the PVCs.
Security agencies detained those who attempted to buy votes and those found with multiple PVCs during the presidential and national assembly elections.
The EFCC claimed on Saturday that its agents intercepted a woman carrying 18 voter registration cards in the Badarwa region of Kaduna state during a sting operation.
