Anup Talukdat, who was one of the accused named in the FIR, was arrested in a raid in the area on the charges of kidnapping and murdering Sourav Chowdhury, Additional Superintendent of Police Bhaskar Mukherjee said.
Sourav's body, which was severed into several pieces, was found between Bamungachi and Duttapukur railway stations in the morning yesterday. The 21-year-old student was kidnapped by a gang in front of his house.
It was being alleged that Sourav was killed as he had started a drive against hooch dens run by Shyamal Karmakar, the prime accused in the case, who is absconding.
Trinamool Congress Chhatra Parishad yesterday claimed that Chowdhury was its member and alleged the involvement of the CPI(M) and BJP in his murder.
The two parties, however, denied the charge.
