Over 7,000 policemen have been deployed in Nagpur city amid the loudspeaker row triggered by MNS chief Raj Thackeray, who has told authorities to get them removed atop mosques by May 4 or face the consequences.

Police Commissioner Amitesh Kumar, who chaired meetings with senior officials of his department during the day, said leaders of all communities have been spoken to last month in order to maintain peace in the city.
