Deputy Chief Minister and Home Minister R Ashoka told reporters here that the RAF companies would conduct flag marches in areas where people from the northeast reside in large numbers.
Ashoka said the state government has "definite information" about those who have sent the SMSes that created panic and they would be arrested soon.
Officials said 16,000 northeasterners have fled the city in the past two days, and another 2,000 headed home this afternoon in a special train.
