Memon would be hanged tomorrow morning as the Supreme Court today rejected his plea seeking stay to the execution.
According to police sources, senior police officials here have requested the Muslim religious and community leaders not to make any public statement or speech about Memon after the hanging.
If an inflammatory speech or a remark is made, the police would take prompt action, sources said.
All Deputy Commissioners, Additional Commissioners and Assistant Commissioners of Police have been deployed in sensitive areas in the city.
As a preventive measure police have also rounded up several miscreants especially those who have police record.
