Panaji: Goa Police’s investigation into the Mapusa and Dona Paula robbery cases has revealed that the accused Bangladeshi nationals had entered India from Meghalaya.They planned the robbery in Goa when one of them was in Colwell jail, where he developed his network. This person used to come to India every six months since 2010 to commit robberies in different parts of the country.Bangladeshis do Reiki for about two days to understand the sleeping patterns of families. The accused escaped with goods worth Rs 55 lakh – Rs 35 lakh in the Dona Paula robbery and Rs 20 lakh in the Mapusa robbery.DGP Alok Kumar said that the accused persons were identified by the Goa Police long ago and now, the main accused has been arrested. Kumar said that after the crime he fled to Bangladesh. The five arrested are Noor Islam alias Nadeem Khan, Mohammad Saiful Islam, Sattar Khan, Zakir Hauladar and Mohammad Sumon Hauladar from Bangladesh.Crime Branch SP Rahul Gupta said that it has been found that he had crossed the border from Meghalaya. Since one of them, Noor Islam, already has a criminal history in Goa, he is familiar with Goa and was instrumental in bringing the rest of the gang members to the state.He said, “Noor Islam was in Colwell jail for about 22 months, and he was transferred to a jail in Andhra Pradesh, where he got bail. After that, he returned to Goa to commit robberies. He developed his criminal network in the jail and used the same to carry out the robberies.”“Some of the gang members conducted recce of the targeted residential areas and the accused persons stayed in nearby secluded/forest areas for a day or two and observed the sleeping patterns of the residents,” Gupta said. “They also studied the number of family members and the easiest entry into the house. They divided themselves into small groups of two to three to avoid being noticed.”Gupta said the accused persons used to have fixed meeting points like bus stands, railway stations and beach areas. “They did not use technical methods of communication to avoid detection,” he said.The accused were equipped with weapons like rods and knives in case they threatened the residents and faced retaliation. The source of these weapons is still being established.Upon gaining unlawful entry into the said bungalows, the accused persons evaluated the internal layout, identified closed and open rooms, and selectively targeted accessible areas for robbery.“While committing the crime, the accused assaulted and tied up the family members present in the house and then committed robbery by snatching gold ornaments and other valuables,” Gupta said. Goa Police teams were sent to Belagavi, Bijapur, Bengaluru, Hyderabad, Kolkata, Delhi, Guwahati, Tripura and Meghalaya. Gang members identified and details shared with state police departments
