Fraud Anatomy
Digital arrest scams
and what apps can see
In a digital arrest scam, fraudsters pose as police or agency officials, claim the victim is under investigation and keep them on a call while they press them to transfer money. The customer approves the payments, so the evidence is on the phone and in the session.
What is a digital arrest scam?
The script is consistent. A call or WhatsApp message claims the victim's Aadhaar, SIM or parcel is linked to a crime. A video call with a uniformed "officer" follows, and the victim is told not to disconnect or tell anyone. The "case" is closed only if the money is moved to a "safe" account. Fear and isolation do the work.
Because the victim authorises every transfer on their own phone, the bank's usual checks see a genuine customer, on a genuine device, entering a correct PIN.
A 2026 case in Goa
In July 2026 the Enforcement Directorate searched 20 locations across Goa, Mumbai, Delhi and Kolkata over a scam in which a senior citizen in Goa lost ₹2.6 crore. Fraudsters posed as TRAI and CBI officials on phone and WhatsApp and threatened a fabricated "digital arrest". The agency froze more than 400 bank accounts used to route the proceeds and seized cash, foreign currency, gold and property papers.

Signals on the phone during a guided payment
An app cannot hear the call. It can see what the call does to the session:
- A remote-access or screen-sharing tool running while a payment is made.
- A first-time payee, a large amount, or an unusual time for this customer.
- Behaviour that looks guided: long pauses, copy-and-paste of account numbers, and step-by-step navigation unlike the customer's normal use.
- A new device, a new network or an impossible location.
- Several accounts receiving money from many victims, which points to mule accounts.
What to do with those signals
A risk engine scores the signals together. A high score can step up the payment (an extra confirmation with a plain-language warning), delay it, or block it. The signed evidence record keeps a defensible trail for the bank, the customer and the investigators.
NonaShield does this with behavioural detection, screen-sharing detection and risk scoring. It reduces the chance a guided payment goes through. It cannot stop a customer who passes every check and is determined to pay, which is why the warning step matters.
Frequently asked questions
What is a digital arrest scam?
A fraud in which criminals pose as police or agency officials, claim the victim is under investigation and keep them on a call until they transfer money to a "safe" account.
Can a banking app detect a digital arrest scam?
Not the call itself. It can detect the signals around it, such as screen sharing, a first-time payee, unusual amounts and guided behaviour, and step up or block the payment.
Is there a real digital arrest?
No. Government advisories state that there is no such thing as a digital arrest, and genuine agencies do not demand money over a video call.
What should a customer do?
Hang up, do not transfer money, tell a family member, and report on the 1930 cyber helpline or cybercrime.gov.in.
