Reports say Atorough was abducted at his post in Ibafo, notorious for pipeline vandalism and oil theft on May 11 2016.
The alleged militants operating around the creeks in the area were flagged down by the corporal and three of his colleagues at about 8.30pm.
Rather than wait, the driver of the snatched car in which the militants traveled zoomed off. This prompted Atorough to chase them with a motorcycle alone.
However, since he went after them, he is yet to be seen.
His colleagues were said to later trail the alleged gunmen but could not find them or the corporal who is from Benue state and has five children.
The police, after a futile effort to get their colleagues later arrested the owner of the car and three other suspects. The other three police officers were also detained.
One of the arrested suspects confessed that the police officer was with his colleagues.
Wilson Atorough, who came from Benue as a result of the incident, said corporal Atorough had earlier complained that he was suspecting some of his colleagues at the police division.
