Mumbai: The social networking sites were today found spreading certain rumours that the Brihanmumbai Municipal Corporation (BMC) has declared a 'red alert' in seven cities, including Mumbai, following the heavy rainfall.

According to the forwarded rumours, cities like Ahmedabad, Surat, Baroda, Mumbai, Thane, Pune and Nasik are about to face the highest rainfall ever in the next 24 hours.

On behalf of the BMC, the rumours further declared a red alert and sent messages through social networking sites that there is a possibility of cloud burst.

Such messages have created panic among the public.

On Thursday, after the city witnessed a heavy rainfall, Indian Meteorological Department (IMD) warned the BMC of heavy to very heavy rainfall in the next 48 hours, which resulted in some wrong interpretations and such rumours were spread in the public.

Consequently, BMC's disaster management department has made a complaint to the police that rumours of cloud burst are being spread among the public.

Assistant Police Inspector from the police control room said, "We are trying to trace the person who started spreading these rumours. We will monitor the social networking sites and investigate further."
