The arrest of suspected terrorist Faisal Mirza may just have exposed a double threat posed to the city by the Lashkar-e-Taiba (LeT) and Islamic State (IS, also known as ISIS). Mirza, 32, was arrested in May after he returned from alleged training at LeT camps in Pakistan. He has told investigators that IS handlers were also present as motivators in the camps during his training.

This is the first time the IS angle has come up in the case. Sources in the Anti-Terror Squad said that they will now probe if Mirza has been in touch with any IS operators or handlers in India.
