Mohasin Shaikh, 28, a resident of Bankar Colony in Hadapsar, was bludgeoned to death wih hockey sticks allegedly by a group of men with links to Hindu Rashtra Sena(HRS) during protests after an objectionable post was uploaded on Facebook by unknown people which denigrated warrior king Chhatrapati Shivaji and Shiv Sena chief late Bal Thackeray.
The move by authorities came even as the newly elected BJP MP from Pune Anil Shirole made a controversial statement that though the incident (murder) was "unfortunate" the repercussions of the derogatory post were "natural".
"What happened is unfortunate but after the Facebook post some repercussion was natural," he said, but hastened to add "we are making all efforts for restoring peace in Pune, people there want peace."
Some media reports said the posts might have originated from Internet Protocol(IP) addresses in a foreign country but there was no official word on it.
