Back in October, Microsoft helped Delhi police’s cyber cell bust 10 companies that were illegally running call centers whose employees posed as tech support staff and duped Windows users based in the United States. Continuing the crackdown, law enforcement officials from Gurgaon and Noida have now arrested 39 more people after raiding 16 call centers involved in a similar scam, but on a wider scale.

During the crackdown, the law enforcement officials found incriminating evidence at the fake call centers such as call log transcripts, materials used to train the employees for posing as genuine tech support personnel, live chat history detailing the conversation with victims and payment gateway records.
