Jagroop Singh, a suspect in a railway track bombing attempt in Patiala, Punjab, died when an improvised explosive device detonated prematurely. Investigators found he had been in contact with a handler named Jujhar Singh in Malaysia through the encrypted messaging app Threema. Following the incident, Punjab Police uncovered a terror module linked to Pakistan and arrested four individuals, including the alleged kingpin Pradeep Singh Khalsa. The investigation revealed that Jagroop had traveled to Malaysia multiple times between 2014 and 2022, establishing connections with operatives involved in attacks on public infrastructure. Authorities are also examining his potential involvement in previous incidents, including a blast in Sirhind and another explosion in Moga earlier this year. The Khalistan Zindabad Force claimed responsibility for the bombing and threatened further attacks in an audio message attributed to its operative.
