Heavy security was deployed at several places in Mumbai and adjoining cities on Wednesday, a day after MNS chief Raj Thackeray urged people to play the Hanuman Chalisa on loudspeakers wherever they hear loudspeakers "blaring 'azaan'.
The morning prayers were offered peacefully at many mosques, an official said. All senior police officials, including Mumbai Police Commissioner Sanjay Pandey, were out to take stock of the security deployment, he said.
Police were also deployed outside mosques at some places.
There was nakabandi' (blockade) at various locations and vehicles were being checked since the early hours to avoid any untoward incident, the official said.

Heavy security was also deployed at many places in neighbouring Thane and Palghar districts.
