The CBI has arrested a telecom company's area sales manager in Delhi as part of 'Operation Chakra-V' for allegedly facilitating the illegal bulk issuance of approximately 21,000 SIM cards. These SIMs, procured in violation of DoT norms using fraudulent KYC and dummy individuals, were used by cybercriminals for phishing and other scams. The probe, linked to a December 2025 bust of an NCR-Chandigarh phishing network, has expanded to western Uttar Pradesh, with telecom firms in the region now under scrutiny.
