The Department of Telecom (DoT) has directed telecom operators to block 28,200 mobile handsets and carry out immediate reverification of 20 lakh mobile connections for their alleged link with cyber crimes, according to an official statement on Friday.

DoT, Ministry of Home Affairs (MHA), and state police have joined hands for curbing the misuse of telecom resources in cyber-crime and financial frauds and aim to dismantle networks of fraudsters and protect citizens from digital threats, it said.

"Analysis carried out by MHA and state police has revealed that 28,200 mobile handsets were misused in cybercrimes. The DoT further analysed and found that a staggering 20 lakh numbers were used with these mobile handsets.

"Subsequently, DoT issued directions to telecom service providers for pan India blocking of 28,200 mobile handsets and to carry out immediate reverification of 20 lakh mobile connections linked to these mobile handsets and disconnect failing re-verification," the statement said.

The DoT launched Chakshu portal two months ago to handle telecom fraud-related grievances.

Since the launch of the portal, the department has blacklisted 52 entities involved in sending malicious and phishing SMSes, blocked 348 mobile handsets across the country, and flagged 10,834 suspected mobile numbers for re-verification.

Besides, DoT has blocked 1.58 lakh unique mobile device identification number IMEI due to involvement in cyber crimes and financial frauds or mobile connections taken on fake or forged documents.

Till April 30 this year, DoT disconnected 1.66 crore mobile connections, of which 30.14 lakh were disconnected based on users' feedback and 53.78 lakh for exceeding individual limit to buy new SIM cards, as per official data.
