The suspicion of the involvement of the KLO follows the release of Faizul Islam, who was kidnapped with Pathak.
The Police sources said that KLO has some bases in the districts of Dhubri and Bongaigaon and the involvement of the group in the incident can be alleged.
The criminal involved in the killing of Pathak used small arms and the involvement of frequent criminals to earn some easy money also cannot be ruled out.
Sources said that Faizul Islam, who was kidnapped with Pathak, was released near Chapar in Dhubri district last evening and a police officer conduct him back to Bongaigaon. As Islam’s health condition was not fine, he has been admitted to the Bongaigaon civil hospital.
