BANGALORE — Thousands of Indians have fled southern and western cities in response to text-message warnings and threats said to be from Indian Muslims angered at recent ethnic clashes in the northeast. Thousands of northeasterners who work and study in Bangalore – India’s 4th largest city and information technology hub – are fleeing, fearing that recent violence in the northeastern state of Assam, which displaced some 300,000, would spread south. Rumor and fear-mongering seem to be trumping hard evidence of any real threat for many of those leaving, however. “There was some talk about text messages saying that people would be attacked. But we do not know, really,” says 18-year old civil engineering student Takan Sama minutes before his train to Assam was slated to depart Bangalore rail station.
