According to a senior police official, a letter in this regard was received at the two cineplexes in which the sender asks the management not to screen a film produced by Balaji Telefilms "as it is against Hindu culture".
"The sender has neither specifically identified the movie nor the organization to which he belongs. The management informed us about the incident after which preventive security steps have been taken," the official said.
Efforts are being made to identify the sender, police said.
