A 17-year-old youth was hacked to death in Puducherry by members of an unidentified gang on Wednesday night. The gang decapitated his head and threw into police premises in Cuddalore.
The body of the deceased, identified as Swethan, was dumped in a lake bed in Bahoor village of Puducherry.
Police of both the neighbouring Cuddalore district of Tamil Nadu and Puducherry are probing the incident.
The police said that the act was recorded on a CCTV camera near the police station and three persons were arrested in connection with the case on Thursday.
The body was shifted to the Puducherry government hospital for post mortem.
Senior Puducherry police officer Rajiv Ranjan told NDTV that the Investigation is on and a person named Vinod is the main accused in the case.
“The gang’s suspicion that the youngster informed the police about their crimes appears to be the motive”, he said.
