Sports desk : The Delhi Police has been instructed to increase security after the NIA received a letter claiming the Indian cricket team is under threat. India will play a T20I series against Bangladesh with the first game scheduled in Delhi on November 3. 

It appears that the Indian team might be under the threat of a deadly attack in the capital. The letter received by NIA has been forwarded by the security agency to the Board of Control for Cricket in India (BCCI) and the Delhi Police has been asked to beef up security ahead of the two team's arrival. The anonymous letter says 'All India Lashkar' based out of Kozikhode might target Indian captain Virat Kohli and prominent politicians, who will be present at the Arun Jaitely Stadium for the first T20I. However, Kohli is not a part of the T20I squad for the Bangladesh series and Rohit Sharma will be leading the side in his absence. 

According to sources, the letter could be a hoax but given heightened threat perception no chance is being taken and security review of the match venue and individual players is being done.

 The Indian team will be starting favourites against Bangladesh, who are likely to be without star all-rounder and T20I skipper Shakib al Hasan for the one-month-long tour. India head into the series on the back of a Test series whitewash over South Africa, who were hammered 3-0 in the recently-concluded three-match Test series.
