Bengaluru: Karnataka Chief Minister Jagadish Shettar on Friday ordered an inquiry into the rumour-mongering about alleged security threats that triggered an exodus of people from northeastern states from the tech hub since late Wednesday.

About 240,000 people from the northeast region live in Bengaluru and another 100,000 in other cities across Karnataka.

“The chief minister informed members of parliament from the state in New Delhi that he has directed police to investigate the wild rumours against northeast people in Bengaluru and alleged threats to their students as a backlash against the ethnic violence in Assam,” an official of the Chief Minister’s Office told IANS here.

Though no untoward incident occurred since Thursday and no threat complaint was received by police here, security has been beefed up in sensitive areas across the city.

Police have intensified patrolling in localities populated by northeast people, including college-going students, blue-collar and white-collar employees, security guards and women working in beauty salons.

“We are getting calls regularly on the two helpline numbers set up in the city control room. But they are general, to find out how the situation is, if threat calls are being made, and if anyone has been attacked. No specific complaint against anyone so far,” Bengaluru Deputy Commissioner of Police (intelligence) Vincent S. D’Souza told IANS.

While the state government, right-wing Hindu outfits like Sri Rama Sena and Rashtriya Swayam Sevak (RSS), Muslim organisations and civil society exhorted the northeast people, especially students, not to leave the city or the state, about 4,500 more of them left late Thursday in four special trains bound for Guwahati in Assam.

“As about 4,600 unreserved tickets were sold till late Thursday, we had to arrange at short notice two special trains of 20 coaches each to Guwahati to clear the extra rush of passengers and attach five more coaches to the two daily trains to northeast stations [Guwahati and Howrah] from the city,” South-Western Railway (SWR) spokesman Suvankar Biswas told IANS.

As part of the investigation, cyber sleuths attached to the city police crime branch have started cracking at the sensational messages sent through SMS and MMS, e-mails and postings on social media sites like Facebook and Twitter that caused panic and fear among the people from the region.
