"We received the information that six terrorists have come to Tamil Nadu and they are moving towards Coimbatore. And so we have increased the security at shopping malls, important temples and at important installations.
"We have also informed the army and air force to alert their defences. We have also put vehicle checking points all over the city. As of now, a general red alert is maintained. There is no need to worry and panic," Sumeet Saran, Coimbatore Police Commissioner, said.
The police have deployed 10 Quick Reaction Teams (QRTs) at strategic locations as a precautionary measure, and almost 2,000 police personnel have been deployed for securing the city.
Further details awaited.
