A 31-year-old professor of Applied Mathematics was arrested for allegedly threatening to blow up a coaching institute in northwest Delhi’s Wazirpur Industrial Area, police said.
The accused, Bachchu Jha, a resident of Madhubani in Bihar, taught Applied Mathematics in colleges of Haryana and Bihar. He was apprehended from Nashik in Maharashtra within 18 hours of making the extortion call.
According to the police, Jha telephoned the institute on April 2 at 11.42 a.m., posing as “Babla Gujjar” from Noida, and demanded ₹21 lakh. He allegedly threatened to carry out a bomb blast if the payment was not made. After the institute’s authorities filed a police complaint, an investigation was initiated.
A special team analysed call detail records, subscriber information, and the caller’s digital footprint to trace his location to Nashik. The team travelled over 2,800 km to apprehend him.
According to the police, the accused targeted the institute as it is a well-known establishment, with the intention of making quick money. An FIR has been registered under relevant provisions of the Bharatiya Nyaya Sanhita for extortion, criminal intimidation and blackmail.
