An FIR was registered in this case on Thursday, the day when the posts came to light, Shaikh said, adding that the offensive material on Facebook had led to tension in this communally-sensitive city in central Maharashtra.
In the second case, City Chowk police arrested a 24-year-old man, Amit Chavaria, for posting an allegedly objectionable image related to a particular community in a WhatApp group.
"Chavaria was arrested on June 3. He posted the offensive picture on June 1 and the same day an FIR was registered," police added.
The arrests come in the backdrop of uploading of derogatory posts on Facebook that led to violence in Pune last week resulting in the killing of an IT professional.
