A threat call on December 6 has put the entire state police force on high alert. The caller claimed that a few people had entered the city from Porbandar, Gujarat, and were planning to carry out a terror strike at all busy railway stations, including CSMT, Dadar, and Kurla.

The city police were busy in bandobast at Chaityabhoomi to mark the 66th death anniversary of Dr B R Ambedkar. More than 3 lakh people were present there, including several VIPs, and the threat call put the entire force on its toes.
