Indian-origin Sharath Subramaniam Shankar, who works in the United States, was arrested earlier this week for sending multiple bomb threats, including to the Bombay Stock Exchange (BSE) in Mumbai, courts, five-star hotels and schools. A Look Out Circular (LOC) had earlier been issued against Sharath Subramaniam Shankar after the investigation revealed just one man was behind a number of bomb threats at multiple locations. Shankar was detained by the Tamil Nadu Police earlier this week when he landed in the state. “It is really good technical work done by the Tamil Nadu police which led to his identification,” a senior Mumbai Police officer said, adding, “They had issued a look out circular against him and as soon as he landed, they received an alert and he was placed under arrest.”
