Bhubaneswar: The special task force (STF) of the crime branch has claimed to have got crucial leads in neighbouring West Bengal while investigating the mysterious abandonment of five baby orangutans in Odisha’s Balasore district, with officials now focusing on a suspected vehicle used to transport the critically-endangered primates.STF investigators have painstakingly analysed hundreds of CCTV footage clips collected from Odisha and adjoining areas, helping them reconstruct portions of the route taken by the smugglers. Based on the findings, multiple STF teams have been deployed to track vehicle movements and identify individuals suspected to be part of an organised international wildlife trafficking network. According to an STF officer, they have narrowed their focus to a black SUV whose movement was captured on surveillance cameras shortly before the orangutans were rescued from Bhogarai area.“We have some clues about vehicles used in transporting the animals, but some technical data still needs to be corroborated before we reach a conclusion. The movement of a black SUV captured the previous night is under scanner,” an STF sleuth said on condition of anonymity.The probe has gained momentum after investigators began examining mobile tower data from areas surrounding Bhogarai from the very first day of investigation. Officials believe the telecom data, coupled with CCTV analysis, could help identify the people involved and establish links between different locations used during the transportation of animals.Investigators are also exploring an intriguing clue provided by forest officials and wildlife experts. The rescued orangutans, currently under care at Nandankanan Zoological Park, adapted remarkably well to feeding through milk bottles, showing little hesitation in accepting formula milk offered by caregivers.Forest officials believe this behaviour indicates the infants were likely being raised in captivity before being abandoned. Their familiarity with bottle feeding suggests they may have been kept at a facility or location where they were regularly fed infant formula, strengthening suspicions that the primates were part of an organised illegal wildlife trade network rather than being sourced directly from the wild.
