A Tamil Nadu native was brought to Thiruvananthapuram on a production warrant after city cybercrime police linked him to more than 200 alleged hoax bomb threats against institutions across Kerala since 2023, including the airport, government offices, courts, hotels and temples.
Sharath Subramanyam, who worked in the information technology sector for 12 years and was involved in artificial intelligence research, was arrested by Tamil Nadu police in July 2026 after allegations that he had sent more than 1,500 hoax bomb threats across India. Thiruvananthapuram city police said a team brought him to the state capital after securing the production warrant.
City police commissioner Arul R B Krishna said the accused allegedly sent around 40 fake bomb threat emails to key government institutions and public establishments within Thiruvananthapuram city limits. The reported targets included Thiruvananthapuram airport, Cliff House, the chief minister’s official residence, Lok Bhavan, the governor’s residence, the Secretariat, the district court, the collectorate and five-star hotels.
Police also said an email claiming that explosives, including RDX, had been planted at the German consulate in Thiruvananthapuram triggered security concerns. The alleged threats repeatedly affected the functioning of public institutions. Court proceedings were disrupted after threat messages were sent to court complexes, including the district court, on six occasions.
One incident at the Thiruvananthapuram district collectorate on March 18, 2025, led officials to evacuate the building after a threat claimed that explosives had been planted there. During a subsequent inspection by the bomb squad, a disturbed beehive caused several people, including senior officials, to be stung. Those affected sought treatment at Peroorkada district model hospital and Thiruvananthapuram Medical College Hospital.
The alleged targeting also extended to religious institutions. Police said websites of the Sree Padmanabhaswamy Temple and Attukal Bhagavathy Temple were used to obtain email addresses for sending bomb threats. The threats disrupted devotees’ access to the shrines, according to the report.
The state police chief and the transport commissionerate were also named among the alleged targets. Police said the accused used artificial intelligence to send the threats and then tracked their impact through local news reports. The current proceedings in Thiruvananthapuram follow the earlier Tamil Nadu case concerning the wider set of alleged threats across India.
