MUMBAI, June 4 -- The Maharashtra Anti-Terrorism Squad (ATS) has registered two separate cases under the Arms Act following its search operation across 22 locations in Mumbai and Thane districts connected with suspected terrorist activities, which led to the recovery of swords, choppers and knives from two places. Nineteen mobile phones seized during the searches have been sent to Kalina for forensic analysis and retrieval of data, which police believe could unearth vital clues about the activities of terror suspects. The nearly 12-hour-long search operation on Monday was conducted based on information that people close to Saquib Andul Hamid Nachan, alleged chief of the ISIS module in Maharashtra who is currently in judicial custody for his alleged links with the ISIS module in Delhi, had become active again. Twenty-two persons including seven of Nachan's close relatives in Padgha - his native village in Bhiwandi taluka under Thane district - were detained during the searches and released on Monday evening after being questioned for several hours. According to sources in the ATS, those radicalised by Nachan in Padgha communicated among themselves via imo, an instant messaging and video-calling app which was banned by the central government in May 2023 based on suspicions regarding its use in terrorist activities, especially in Jammu and Kashmir. "We are hoping that forensic analysis of the phones seized from suspects will unearth how they kept in touch and what activities they were planning," a police officer who is part of the investigating team told Hindustan Times. The role of two persons among the 22 questioned by the ATS is especially circumspect, the officer said. "We will interrogate them again once we get some evidence." The Maharastra ATS is also verifying if Nachan, who is currently lodged in Tihar jail, passed on any messages during video calls with his family. Prisoners are allowed to talk to their families via video calls in the presence of jail authorities and the Tihar jail manual indicates Nachan interacts with his family regularly, said ATS sources....
