MUMBAI, June 3 -- The Maharashtra Anti-Terrorism Squad (ATS) on Monday detained and later released two dozen people in connection with suspected terrorist activities after conducting searches at 22 places in Mumbai and Thane districts. Those who were detained included seven close relatives of Saquib Abdul Hamid Nachan, 63, an alleged former office-bearer of the proscribed Students' Islamic Movement of India (SIMI) who was convicted for his role in the 2002-03 serial blasts in Mumbai and is currently in judicial custody for his alleged links with the Islamic State of Iraq and Syria (ISIS). "Around 100 police personnel from Mumbai, Thane and Navi Mumbai units of the ATS conducted searches at 22 places, in teams of four-five policemen," said a senior police officer. The searches were initiated based on specific information that people indoctrinated by Nachan had become active, and warrants had been obtained from the court to search premises related to them, the officer said. The searches commenced late at night on Sunday and continued till Monday afternoon. Apart from Saquib Nachan, searches were conducted at the premises of his close relatives Aaquib Saquib Nachan, Abdul Latif Kaskar, Kaif Nachan and Shajil Nachan. The ATS also searched the residence of Hasib Mulla, who had been arrested by the NIA along with Saquib Nachan in December 2023 for their suspected links with ISIS. Around two dozen suspects including seven of Nachan's close relatives were detained for questioning after swords, knives, and documents promoting terrorism were found in their homes. Nachan and Mulla were among 15 persons arrested by the NIA on December 9, 2023, following searches at 44 locations in Maharashtra and Karnataka....
