The police claimed that allowing such a symposium which dealt Shivaji's views on Muslims would give rise to law and order issues, due to which permission to the event was denied.
Organisers had never asked permission for the event which the police learnt about through the media.
Meanwhile, Awhad and others condemned the police for not allowing the symposium and termed it "crushing democratic rights".
