The police have not ruled out the possibility of an old enmity in connection with the incident.
According to Niwari SHO Sanjay Tyagi, agricultural labourer Yograj (27) and a boy, Jitendra, were irrigating the fields last night when three men arrived at the spot, thrashed both of them and abducted Yograj.
On being alerted, police reached the spot and launched a hunt, he said, adding that the fields and forests in the area were being combed by the force but till last reports came in, there was no breakthrough.
Naresh has told the police that Rahul had a strong suspicion that Yograj had an illicit relationship with his wife.
Police are raiding all the possible hideouts of Rahul, said the SHO, adding that a case of kidnapping has been registered.
