Satendra Siwal, an Indian Embassy security guard in Moscow, was arrested by the Uttar Pradesh Anti-Terrorism Squad (ATS) for allegedly spying for Pakistan's Inter-Services Intelligence (ISI). Siwal, also a Ministry of External Affairs staff member, confessed to sharing sensitive information with a woman Pakistani intelligence operative for money. The authorities are investigating the ISI's modus operandi in Moscow, and Siwal's bank accounts will be analyzed to determine financial transactions. The incident is seen as a serious breach, and the Indian embassy in Moscow handles critical diplomatic missions.
