A delegation of Rajasthan Muslim Forum recently visited the village and spoke to families of victims there.
"There is an atmosphere of fear in Gopalgarh even after so many months. We demand that the then SP and Collector be arrested and the matter be investigated impartially by the CBI," a release by the forum said today.
A land-related dispute between the Gujjar community and a minority community turned violent in September last year, prompting the police to open fire.
Ten people of the minority community were killed in the firing.
The matter is under investigation by the CBI.
