The Mumbai Traffic Control Room received a terror threat hoax message on its official WhatsApp number on Thursday evening.

According to sources, the threat was sent from a mobile number in which the sender claimed that multiple human bombs in vehicles were planted across the city and warned of a large-scale attack involving RDX. The caller, identifying himself as a member of a Pakistan-based jihadi group, further alleged that 14 terrorists had entered the city.

The threatening message was immediately relayed to the Main Control Room. Police have launched a probe into the sender and are verifying the authenticity of the threat.
