The officials, who came in an unmarked white Toyota Hiace bus, arrived at Obi’s house but the candidate was absent.
They, however, did not grant interviews to journalists and no reason has been ascertained for the purpose of the visit.
The EFCC team lead also had a brief chat with Obi who was on his way back from a tour of the village, Punch reported.
The team left the polling unit, promising to come back soon.
Obi has since voted after waiting on the queue until it got to his turn.
