The suspects assassins also killed a 38-year-old man, Nanman Lamak, who hailed from Jos, Plateau State.
Both men were together when the assailants struck around 9pm.
According to Punch, the bank worker, who reportedly owned a guest house in the area, known as Benex Hotel, was on his way to drop off two guests he carried in his Honda Civic when they were attacked.
PUNCH Metro reports that Okwudiri was giving Lamak a lift in his car and another lady, whose identity had yet to be identified, when the killers, who were said to be in another car, cornered their vehicle.
They were said to have shot dead the duo before fleeing the scene.
Sources said that it was a clear case of assassination, adding that the gunmen shot the two men repeatedly and did not steal any of their belongings.
“They cornered the vehicle, shot Okwudiri and Lamak continuously until they died. The gunmen did not take anything from them, not even their phones,” a source said.
The lady involved has since been arrested by policemen from the Okigwe Area Command.
An eyewitness said the gunmen also shot two other persons at Njeagwake Okigwe town.
