The Delhi Police have arrested a man from Rajasthan for allegedly assisting Pakistani Intelligence Operatives (PIOs) by providing Indian mobile SIM cards for espionage purposes, officials said on Thursday.

The accused, Kasim (34), had travelled to Pakistan twice, first in August 2024 and again in March 2025, staying for about 90 days on both occasions, they said.

During these visits, he is suspected to have met officials from Pakistan’s intelligence agency, the Inter-Services Intelligence (ISI), according to a senior police officer.

Kasim, a resident of Gangora village in Deeg district, was taken into custody earlier in the day and is currently under police remand, the officer said.

“In September 2024, the Special Cell received intelligence inputs that Indian mobile numbers were being misused by PIOs to gather sensitive information related to the Indian Army and government establishments. These mobile SIM cards were allegedly procured in India and sent across the border with the help of Indian nationals,” the officer said.

PIOs used these Indian SIM cards on social media platforms to contact Indian citizens and extract classified information related to critical installations and departments, the officer added.

Following the intelligence inputs, a case was registered under the relevant legal provisions and an investigation was launched. Kasim’s name emerged during the probe, which also uncovered his travel history to Pakistan and possible links to ISI operatives.

Police said the investigation is ongoing to uncover the full scope of the espionage network and identify other Indian collaborators involved in the conspiracy.
