Thackeray died on 17 November 2012, of cardiac arrest. Mumbai came to a virtual halt immediately as the news broke out about his death, with shops and commercial establishments shutting down. The entire state of Maharashtra was put on high alert. The police appealed for calm and 20,000 Mumbai police officers, 15 units of the State Reserve Police Force and three contingents of the Rapid Action Force were deployed. It was reported that Shiv Sena workers forced shops to close down in some areas. The then Prime Minister Manmohan Singh called for calm in the city and praised Thackeray's "strong leadership", while there were also statements of praise and condolences from other senior politicians such as the then-Gujarat Chief Minister Narendra Modi and the BJP leader and MP (Former Deputy Prime Minister of India), L. K. Advani.
