New Delhi, June 15 :     Officially Delhi police and the CBI said they had never heard of Mukesh Gupta or 'MK', the bookie Hansie Cronje has mentioned, but sour-ces here disclosed that a senior cricketer's cellphone kept under surveillance by an investigating agency based in Mumbai between August last year and April this year had thrown up the name. Gupta, a known bookie, operates in Delhi and Mumbai. Others expressed doubt if Mu-kesh Gupta was the real name. They suggested 'MK' could also be the name of a Delhi-based bar-on among bookies, Mohan Khattar. Khattar was on the hitlist of Delhi police and his name was revealed by Rajesh Kalra during the initial stages of investigation. Kalra was arrested just before the Cronje scam broke. Similarly, the other Indian bookie's name mentioned by Cronje matches that of another bookie whose house was raided by Delhi police after Kalra's interrogation. Cronje refers to a person called Sunil. Khattar, Hans and Sunil are the three bookies Delhi police were trying to track down initially. Sunil alias Bittu, as identified by Delhi police at the time, used to stay at Lajpat Nagar. All three are absconding. Kha-ttar may have escaped to the US. Sunil was described by the police as an errand boy for big sharks like Khattar. But the police said Cronje may not be referring to the Sunil named by Kalra. There was tension between the Enforcement Directorate and Delhi police over the bookies' disappearance. The ED suspects that the bookies were tipped off.
