Delhi Police have arrested a 47-year-old man from Karnataka’s Mysuru for allegedly sending over 1,100 hoax threat messages targeting schools, high courts and government offices across the country.

Police said Srinivas Louis was apprehended from his rented house on Thursday following a coordinated operation by Delhi Police and local police teams.

The arrest came after the Delhi High Court, Assembly, and multiple education and government institutes received bomb threats in the recent weeks. “These threats had led to heightened security measures, evacuations and disruption of normal functioning at several institutions. In one such instance, a judge of the Delhi High Court had also lodged a formal complaint after receiving a threat email,” an officer said.

Louis, a postgraduate and a native of Bengaluru, is currently unemployed and living with his mother, a retired government employee. Officials said initial investigation suggests he might be suffering from mental distress. “He deliberately targeted prominent institutions, including courts and educational establishments, to maximise panic,” an officer said.
