Chinwe Obi, a building materials dealer, was shot and his wife, Rosemary, was kidnapped by suspected gunmen in Lokoja, the Kogi State capital.
The couple was said to be on their way home from work when the incident occurred at the Peace Community intersection.
It was discovered that the gunmen had followed Obi and fired at his car, forcing him to stop.
They were said to have taken his wife and then abandoned him in the vehicle with the injuries he sustained while battling them.
SP William Aya, the Police Public Relations Officer, confirmed the incident and said the command was on the trail of the kidnappers.
Aya also said the Commissioner of Police, Edward Eboka, visited the scene of the incident and assured that the perpetrators would be fished out.
He, however, called on anyone with useful information to contact the police.
