The Punjab Police have arrested a man who has a strong connection with Pakistan's spy agency ISI and the top Khalistani terrorist Gopal Singh Chawla, media reports said.

The arrested person was identified as Gagandeep Singh.

The accused shared sensitive classified information, including details of troop deployments and strategic locations, posing a serious threat to national security, officials told India Today.

According to reports, he shared critical information on Army movements and even Operation Sindoor, with agents present across the border.

"Preliminary investigation reveals that Gagandeep Singh had been in touch with Pakistan-based Khalistani supporter Gopal Singh Chawla for the past five years, through whom he was introduced to the Pakistani Intelligence Operatives (PIOs). He also received payments from PIOs via Indian channels," the Director General of Punjab Police, Gaurav Yadav, told the news channel.

Police told India Today that the mobile phone recovered from him revealed critical information about the intelligence he shared with his Pakistan agents, and he had over 20 ISI contacts.

  The crackdown follows the April 22 terror attack in Pahalgam, after which Indian security agencies intensified their counter-espionage operations.

At least 12 individuals have been arrested in recent weeks from Punjab, Haryana, and Uttar Pradesh, as part of an ongoing probe into what officials suspect is a wide-reaching Pakistan-linked spy network operating across northern India.

Among those arrested are two women with a prominent digital presence.

Jyoti Malhotra, a resident of Haryana, had over 3.77 lakh YouTube subscribers and 1.33 lakh Instagram followers, while 31-year-old Guzala from Punjab was also taken into custody.

Both were allegedly in contact with Pakistani officer Ehsan-ur-Rahim, also known by the alias Danish.

Rahim was posted at the Pakistan High Commission in Delhi but was expelled.

The NIA is continuing its investigation into the espionage network and is expected to make further arrests as evidence is analysed.
