Acharya, on basis of TOI reports, had filed a court complaint against Bajrangi for threatening multiplex owners and pressurising them not to release the film 'Parzania', based on Gujarat's communal riots.

On Wednesday Natwarlal's brother, Mukund Acharya filed a missing person's report at the Mehsana taluka police station. Police officials said: "According to Mukund, Natwarlal had left home on March 17 morning, saying he was going to the Mehsana district court. He had promised to come home for lunch, but he never returned."

Mukund Acharya, brother of Natwarlal told TOI over telephone: "We are taken aback at this development. There has been no word from him since. We fear for his safety."

Mukund also said: "Babu Bajrangi's men had come here soon after the court complaint and asked my brother to withdraw the complaint. However, we cannot conclusively say whether he has been kidnapped or has left home on his own."

Police officials said that Acharya's financial condition is also being probed as a possible reason behind his sudden disappearance.

In a letter to governor, Nawal Kishore Sharma, Acharya had said that the Gujarat government had kept silent on the issue and not taken any action against Bajrangi.
