Maryland | A sweeping fraud investigation in the US state of Maryland has uncovered a cybercrime network linked to three India-based call centres, responsible for siphoning off more than ₹400 crore from victims across the United States. Officials said over 650 people were targeted in what is being described as one of the largest coordinated overseas call-centre fraud operations in recent years.
Montgomery County authorities, disclosing findings from a year-long probe on Monday, said the operation relied on sophisticated social engineering tactics to manipulate victims into transferring large sums of money.
According to prosecutors, callers alternated between posing as tech support executives and US law enforcement officials, exploiting fear and confusion to extract payments.

The investigation gained momentum after a 58-year-old woman reported losing nearly ₹14 crore in a single scam. That complaint helped investigators connect hundreds of similar cases, eventually tracing them back to the same three call centres operating out of India.
Authorities said victims were typically contacted via phone calls or alarming computer pop-up alerts claiming their devices had been compromised. Once engaged, scammers persuaded targets to grant remote access, harvested personal data and directed them to move funds through wire transfers or digital payment platforms.
In several instances, fraudsters impersonated federal agents or police officers, warning victims of fabricated criminal investigations and pressuring them to immediately move money into so-called “secure accounts” — accounts that were, in reality, controlled by the fraud network.
Montgomery County State’s Attorney John McCarthy said the case highlights the growing sophistication of cross-border cybercrime.
“These are highly organised operations that prey on fear and uncertainty,” McCarthy said. “Victims suffer devastating financial and emotional losses, while the networks behind these scams are becoming increasingly professional.”
Investigators estimate the three call centres collectively targeted more than 650 individuals, many of them elderly, wiping out lifetime savings, retirement funds and investments. While confirmed losses currently stand at over ₹400 crore, officials believe the actual figure could be significantly higher.
Law enforcement agencies have begun coordinating with federal and international partners. Digital evidence, call records and banking trails have revealed a structured hierarchy within the network, including recruiters, call agents, technical facilitators and money handlers.
Although no arrests have yet been announced overseas, US authorities confirmed that Mutual Legal Assistance requests are being prepared to facilitate action in India.
Cybercrime experts warned that such scams remain widespread and evolving. Police urged citizens to be cautious of unsolicited tech alerts or calls claiming to be from government agencies, avoid granting remote access to unknown parties and never rush financial transfers under pressure.
Officials also advised victims or suspected targets to immediately contact local police or federal cyber helplines so accounts can be frozen in time.
The Maryland investigation comes amid mounting concern in the US over international scam syndicates. Authorities said efforts to dismantle the network and recover funds are ongoing.
