Four mobile phone numbers, which were shared with the Mumbai traffic police in a message warning of 26/11-type terror attacks, are keeping the intelligence agencies and the Crime Branch on their toes. Reason: these numbers have been switched off since February, according to sources.

Last week, an unknown person, believed to be from Pakistan, sent a WhatsApp message to the number of the traffic police department, sources said. The person shared 10 mobile numbers, claiming that the people these belong to are planning terror attacks in the city, like the ones in 2008, and Udaipur-like beheadings, too.
