A prankster kept the railway police and passengers on tenterhooks for more than an hour by claiming that explosives were planted on a train passing through the Tirupati railway station. Tension prevailed at the station as the railway police and bomb squads began searching the Mumbai-Nagercoil Express as well as the Tirupati-Rameswaram train on Sunday. According to police, an unidentified person called up the Madurai railway station in the neighbouring Tamil Nadu at around 4 am and claimed that they were going to blow a train coming to Madurai from the pilgrim town of Tirupati. The Madurai railway officials immediately informed their higher officials in Chennai, who in turn alerted the Tirupati officials. Tirupati railway officials swung into action and undertook checkings in two trains, which were scheduled to proceed through the Madurai station. They heaved a sigh of relief after nothing was found in the trains or the premises of the railway station. Speaking to Express, Tirupati government railway police sub-inspector Bhaskara Babu said passengers in both trains were not disturbed by the checks as one of the trains was scheduled to start from Tirupati itself, while the other was having a 75 minute halt here. “We finished checking and passengers did not experience any sort of inconvenience,” he explained. Meanwhile, it was learnt that checking became a tough task for the railway police wing. “As the railway police does not have any special bomb squad or dog squad team, they have to seek assistance from the local police, which caused some delay,” observed a railway official. Railway GRP DSP Gopalakrishna and others supervised the check ups.
