Four of the nearly 500 Indian nationals rescued from “cyber-slavery” in Myanmar were from the national capital, a Delhi police officer said on Sunday.

“Cyber-slavery” refers to the trafficking of individuals through fake job offers, who, upon joining, are coerced physically and psychologically into participating in organised cyberfraud activities.

Three of the Delhi victims were trafficked in August, and the fourth followed a few days later, according to the officer.

Their operators allegedly told the victims to pay $4,000 for their release or remain captive and work as cyber fraudsters. They were trafficked on the pretext of high-paying data-entry jobs in Thailand, but were forced into cybercrime operations.

The officer said various agents recruited the victims – all either 12th pass or graduates – through social media advertisements. From Delhi, they were first taken to Kolkata, then flown to Thailand, and finally transported by river to Myawaddy in Myanmar.
