The violators also desecrated parrh (a piece of cloth wrapped around the idol) at Faqir Par Braham's ashram in Tharparkar district, a Hindu majority area.
The minority Hindu community came out on streets in all the towns of the district and also staged a sit-in at Mithi's Kashmir chowk. Markets in Deeplo, Islamkot and Chachro towns were shut in protest.
"The Hindu community is being targeted in all parts of Sindh under a conspiracy," Raja Bhawan of Tharparkar's Hindu panchayat, who led the protesters, was quoted as saying by Express Tribune daily.
Tharparkar is currently facing a drought-like situation.
