The authorities are also mulling invoking the stringent provisions of Maharashtra Prevention of Dangerous Activities Act (MPDAA) making it difficult for them to secure bail, Pune Police Commissioner Satish Mathur said.
Mohasin Shaikh, 28, a resident of Bankar Colony in suburban Hadapsar, was allegedly bludgeoned to death with hockey sticks by a group of Hindu Rashtra Sena men after uploading of an objectionable post on social networking website Facebook by unknown people which denigrated warrior king Chhatrapati Shivaji and Shiv Sena chief late Bal Thackeray.
Those arrested have been booked under various sections of IPC including murder.
In addition, about 180 persons have been arrested in connection with cases related to the rioting and damaging of city buses in the area in the incidents on Sunday and Monday during the Bandh called to protest against the Facebook post.

Mathur said the role of self-styled chief of HRS Dhananjay Desai in Mohasin's case was under investigation. Desai was arrested in a case filed against him for allegedly circulating inflammatory literature after the violence.
Asked about the possibility of imposing a ban on HRS, Mathur said such a move needed thorough investigation and documentation of the organisation's activities and cannot be taken in a hurry.
The arrested accused were produced before a magistrate who remanded them in police custody till June 9.
The situation in the area continues to be peaceful with no fresh violence in the last two days, police said. An appeal has been issued to citizens not to circulate or forward provocative messages on social media or spread rumours thorough SMS.
