Overview
- A string of hoax emails that claimed bombs at ISRO, the NIA, DRDO, NPCIL, MoCA and an Air India New Delhi–New York flight were sent on Monday, June 29, and prompted security alerts and searches across agencies.
- Delhi Police traced the digital trail from two email accounts to a mobile number and used technical surveillance to locate and arrest a 36-year-old man from Ghaziabad.
- Bengaluru Police seized an electronic device from the suspect and say forensic analysis confirmed it was used to send the ISRO threat.
- No explosives or suspicious items were found during searches, police report the arrested man has a long history of mental illness and investigators have not established a motive.
- A separate hoax email was sent to ISRO the next day by a different sender and police continue parallel probes, with possible legal action and wider reviews of how agencies handle digital threats expected to follow.
