Calcutta, Aug. 21 :    Calcutta, Aug. 21:  A week before the abduction of Khadim's owner Parthapratim Roy Burman on July 25, Swati Pal had visited Dubai and spent a couple of days there, an examination of the arrested bar singer's passport has revealed. Swati was arrested along with her associates Jamil Ahmed and Abdur Rehman in Mumbai in connection with the kidnapping by a criminal gang based in Dubai. While her passport was found to be genuine, the Mumbai address entered in it was false. Swati and her associates were brought to the city this evening and were rushed for interrogation under heavy police escort. The police said the three had visited the city 'some time before the kidnapping' to network with a group of local criminals. The police had earlier traced several ransom calls both to the Roy Burman house as well as to a ring of Dawood Ibrahim associates, who had collected the ransom money in Hyderabad, to Dubai. Yesterday, another 'kidnap facilitator', so far identified as Pawan, had been arrested by the Hyderabad police for siphoning off the ransom money through the hawala route. 'He is part of this entire kidnap drama,' said Hyderabad commissioner of police P. Ramulu. According to Ramulu, Pawan had escorted the Roy Burman family representative who had arrived in Hyderabad on July 29 to hand over the ransom money. 'Pawan was with him for 24 hours till the payment of Rs 3 crore was completed in a city hotel,' he said. Ramulu said Pawan was in touch with both the 'Dubai kingpin' as well as Swati and Jamil. 'The role of the two in this crime is certain because we have printouts of cellphone calls being made by Pawan to these two in Mumbai,' Ramulu said. In a joint raid last night, a Mumbai police-CID team picked up three associates of Jamil Ahmed and Abdur Rehman from Dongri and Bandra. Since Sunday, six different Mumbai police-CID teams had fanned out in different parts of the city, including Tilaknagar, Chembur, Byculla and Santa Cruz to trace the four criminals who had travelled from Mumbai to Calcutta to kidnap Roy Burman from Tiljala. The police had taken Swati, Rehman and Ahmed along with them to act as 'guides'. 'Though the four have so far proved to be elusive, we believe the three who have now been detained will provide fresh information on the kidnapping,' said Mumbai police commissioner M.N. Singh. Singh said the three are also wanted for crimes in Mumbai and may not have any direct hand in the Calcutta kidnapping, but have the potential to take the police to the four missing abductors. 'They are, after all, associates of Rehman and Ahmed who are wanted in several cases of abduction and killings,' Singh said. Another abduction suspect, Rabindranath Das, who used to run an ashram in Salt Lake, Adhwatik Ishwariya Vishwavidyalaya, before his arrest, was grilled by the police for several hours today. The police said he identified Swati as 'Manu', the daughter of an ashram inmate. The police believe Das had given shelter to some of the abductors in his ashram when they had come on their reconnaissance mission to the city.
