Security has been tightened at the Sri Lankan deputy high commission in Nungambakkam after the officials there complained of receiving a threat letter a couple of days ago.

The officials on Saturday submitted to police commissioner S George a post card containing a few lines warning that bombs would go off on the premises of the mission. The letter also condemned the activities of the Sri Lankan government.

Security at the mission was being looked after by a wing called Security Chennai Police. Now, at least 35 personnel, including an inspector, a sub-inspector and eight armed reserve personnel, have been assigned to bloster the existing force. "We have ordered that constant surveillance should be maintained around the area," an officer said.

The letter has been forwarded to the cyber crime wing, while police are making inquiries to find out who sent the letter. (The Times of India)
