How Was Vijay Mallya Allowed To Flee?

A massive political fight broke out between the BJP and the Congress over Vijay Mallya after Congress leader PL Punia on Thursday claimed he saw Mallya and Finance Minister Arun Jaitley meet in parliament's central hall on March 1, 2016 for several minutes. He went to the extent of saying that he is willing to quit politics if CCTV footage doesn't prove what he is saying. Rahul Gandhi directed his criticism at Prime Minister Narendra Modi and asked if he allowed Mallya to flee. The BJP hit back and said the Gandhis ensured that Mallya got loans when his Kingfisher Airlines was going bust. In all this, there is a bigger question - how did the CBI and investigating agencies allow Vijay Mallya to escape?
