“The call was made from 3615188371”. However, the caller did not name anyone in his call.
“After examining the tower locations of the threat callers, we have come to know that three calls came from somewhere in Kolkata, Dankuni and Guwahati”, a senior police official told IBNS. However, these kinds of threat calls are a regular feature, he added.
The security of the Howrah station was on Tuesday, alerted after an unclaimed steel tiffin box was found lying on the station’s platform number 20. Following the discovery, the platforms 20,21 and 22 were cordoned off and all passengers were instructed to leave the platforms.
