Mumbai, Nov. 25 :    Mumbai, Nov. 25:  Mumbai police today readied for renewed gang war as officers despaired of ever trapping notorious gangster Chhota Rajan, who escaped from the guarded fourth-floor Bangkok hospital room yesterday. 'We finally got a chance to catch him, but lost that,' police commissioner M.N. Singh said. 'It will be a tough task to trace him again.' Singh said police apprehended gangland violence in the commercial capital because the Rajan gang was likely to take revenge on Dawood Ibrahim associates for the attempt on Rajan's life in Bangkok on September 15. 'Rajan will try to settle scores with his attackers now that he has escaped,' Singh said, adding that the police had tightened vigil in different areas in the city. After lying low for a while since the attempt on Rajan's life, his hitmen struck early this month when they killed a Mumbai hotelier, a former Rajan associate, on suspicion he had tipped the Dawood gang about Rajan's whereabouts in the Thai capital. Rajan made a dramatic getaway in the early hours of yesterday, escaping through his fourth-floor hospital room window, using a bedsheet as a rope. 'It has to be an inside job,' a senior official said. 'How could he have escaped had at least some of the policemen on watch not collaborated with him?' The official said the Thai police were also not forthcoming with the details of his escape. A member of the investigating team said there was evidence that Rajan used rock-climbing gear. 'The climbing rope was used and we found several pieces of climbing gear such as hooks at the site,' he said. At least two of the seven guards face disciplinary hearings, adds Reuters. Rajan's lawyer Sirichai Piyapichetkul today said in Bangkok that the mobster used the emergency exit at the hospital to escape after paying 25 million baht to a 'two-star' Thai officer, adds PTI. Another official suspected that the Thai police might have let the gangster go at the end of a 70-day deadline yesterday for giving evidence. 'He may have been allowed to leave the country after the deadline was over.' Officials said they were not happy with the Centre's role in the episode. 'The Union home and external affairs ministries have a lot to answer for.' Deputy chief minister Chhagan Bhujbal said the responsibility for Rajan's escape rested with the Centre because 'they have been directly dealing with Thai authorities'. Bhujbal, who is home minister, said the CBI should try to track down the gangster with the help of Interpol. The Centre, however, denied it was linked with Rajan's escape yesterday, reports UNI. 'There is no truth in these conjectures or accusations... The reports in question seem to be a mischievous attempt on the part of vested interests to misguide the people,' an official statement said.
