Based on information that Samad was seen near Banasai village, a joint team was formed under Manish Raman, the Additional Superintendent of Police (Operations), West Singhbhum, on Saturday, Kranthi Kumar said.
They conducted a raid and arrested Samad, he said adding, the accused has confessed to his involvement in the incident during interrogation.
Samad confessed that he and his accomplices had committed the crime at the instigation of self-styled leaders of Pathalgarhi (a tribal custom), the SP said.
'Pathalgarhi' is a practice in which villagers inscribe various tenets on huge stone slabs and ban outsiders in their area.
Five cases under various sections of the IPC were registered against the accused at the Khunti Women police station, Arki police station in Khunti, and at the Tebo, Bandgaon and Karaikela police stations in West Singhbhum district.
Earlier, police had arrested three persons, including a father of a missionary school, last month in connection with the case.
The case has turned out to be a conspiracy of people involved in Pathalgarhi and the Peoples Liberation Front of India (PLFI), police said.
