Itanagar, Sept. 8 -- A look out notice issued by the Arunachal Pradesh police headquarters (PHQ) led to anti-dam activist Bhanu Tatak being stopped from flying abroad on Sunday, senior officials confirmed. Immigration authorities at the Delhi airport cited the notice while preventing her from boarding a flight to Dublin, Ireland, where she was scheduled to begin a three-month course at Dublin City University on September 9. Tatak, a legal advisor with Siang Indigenous Farmer's Forum (SIFF), has been a critic of mega dam projects in the Siang valley, arguing they endanger indigenous rights and fragile ecosystems. State's IGP Chukhu Apa confirmed the lookout notice but declined to elaborate on the grounds. "At least 10 cases have been registered against Tatak, in which she played a leading role, including charges of instigating crowds to violence, leading violent protests, and even encouraging women to manhandle a cabinet minister," Apa said. DCP (IGI Airport) Vichitra Veer said, "No such matter has been reported to Delhi Police as of now... Immigration authorities may give an answer to it."...
