The Crime Branch also called Hindu Rashtra Sena chief Dhananjay Desai for questioning.
A young IT professional was killed, allegedly by members of a radical Hindu outfit, as he was returning home Monday night, after derogatory pictures of Shivaji and Bal Thackeray uploaded on Facebook triggered communal tension across the city over the weekend, police said.
Police identified the victim as Mohsin Sadiq Shaikh, a 24-year-old from Solapur district, who worked as an IT manager with a private firm in Pune. They said seven people, aged between 19 and 24 years, have been arrested. They were associated with the Hindu Rashtra Sena, a radical outfit active in the state, police said.
