In a significant cybercrime case, Karnataka police have arrested 26-year-old Deepa for her alleged role in defrauding Chennai-based software engineer Sudha Karthik of ₹24.89 lakh. The case, which surfaced in February 2025, underscores the growing sophistication of online investment scams and the risks posed even to informed professionals.
WhatsApp Call Sparks Online Investment Fraud
According to the complaint filed at the Chennai City Police East Zone Cyber Crime Station, Sudha Karthik was contacted by an unknown individual via WhatsApp. The caller convinced her that she could earn high returns by participating in an online investment scheme. Initial small profits lent credibility to the scheme, leading her to trust the instructions provided.
The victim joined Telegram groups shared by the caller and followed tasks and investment prompts posted there. Over time, she transferred multiple sums to bank accounts provided by the accused. In total, ₹24.89 lakh was sent in several transactions. When the promised returns did not materialize, Karthik realised she had been defrauded and filed a formal complaint seeking action against the perpetrators.
Police Investigation and Technical Analysis
Following the complaint, the police registered a case and launched an investigation. The East Zone Cyber Crime Inspector led a team that collected and analysed banking records, mobile numbers, and transaction data.
Using advanced technical tools, investigators examined email IDs, phone numbers, IP addresses, and network user IDs used by the accused. The probe revealed that the primary suspect was hiding in Karnataka, prompting immediate action for her arrest.
Arrest and Interrogation of the Accused
Deepa, originally from Tiruvallur district and currently employed at a textile shop in Karnataka, was apprehended and brought to Chennai. During interrogation, one mobile phone used in the scam was seized.
The investigation revealed that Deepa had provided her bank account to cybercrime operators and received funds from victims. Police continue efforts to trace and apprehend other absconding accomplices linked to the case.
The Rising Threat of Online Investment Scams
Experts highlight that such cyber-fraud schemes combine technological exploitation with psychological manipulation. Victims are often lured by initial small gains or promises of high returns, compelling them to transfer significant amounts. Social media and messaging platforms like WhatsApp and Telegram serve as effective channels for executing these schemes.
In this case, the combination of technical sophistication and psychological coercion helped the fraudsters gain the victim’s trust and control over her financial actions.
Precautionary Measures and Awareness
Authorities have urged the public to exercise caution when approached with unsolicited calls, messages, or investment offers. Financial information should never be shared without verification through official channels. Awareness, vigilance, and careful scrutiny of digital communications are key to preventing such scams.
This incident demonstrates that cybercrime is continuously evolving, and even educated and professional individuals are at risk. With increasing reliance on online financial transactions, the need for digital literacy and proactive verification measures has never been greater. Citizens must remain alert to protect themselves from both financial loss and psychological manipulation by cybercriminals.
