The officer allegedly passed on sensitive details about India's secret war plans, drone capabilities, combat aircraft deployments, military exercises and the locations of strategic military installations to the Pakistani operative.
The police have described the alleged disclosures as a serious threat to India's national security and military preparedness.
The wing commander has been in custody for five months in connection with a case registered under the Official Secrets Act.
According to the charge sheet, he remained in contact with the Pakistani operative through WhatsApp between January 12 and April 1, 2026.
He was intercepted on April 1 after allegedly carrying a smartphone into his office.
Nude photos in exchange for classified documents
One of the most startling allegations in the charge sheet concerns the alleged exchange between the officer and the Pakistani operative.
The police claimed that the operative sent a nude photograph to the wing commander, who allegedly responded by sharing a page from a classified IAF war plan.
The accused had reportedly proposed an arrangement under which he would provide one page from the secret war documents for every nude photograph he received.
Secret drone unit, fighter jet deployment among leaks
The charge sheet alleged that the officer shared extensive information about a secret IAF drone unit, including its strength, organisational structure and operational procedures.
The information allegedly disclosed included details of drone trials, operational capabilities, flight endurance and weapon-targeting systems.
He also reportedly revealed potential locations where the drone unit could be deployed during a war-like situation.
Besides drone-related intelligence, the officer allegedly shared information about fighter jet deployments in Leh and a military exercise conducted at the Mahajan Field Firing Range in Suratgarh, Rajasthan.
The police further alleged that he disclosed the locations of sensitive military installations and details of troop deployments during wartime.
Investigators believe such information could provide an adversary with crucial insights into India's military preparedness and operational strategy.
Five subordinate officers' devices targeted with spyware
The investigation has also uncovered allegations of a wider cyber-espionage attempt.
According to the charge sheet, the Pakistani operative sent the wing commander various applications and links allegedly containing malware and spyware that could be used to access confidential information stored on electronic devices.
The officer allegedly facilitated the installation of specific malware and spyware on the devices of five officers serving under his command.
Police suspect that the alleged operation was intended to access sensitive information and communications between these officers and their superiors.
Investigators are examining whether the accused acted alone or whether other individuals were involved in the alleged espionage network.
WhatsApp chats reveal thousands of messages
The Delhi Police has reportedly submitted digital records of communications between the accused and the Pakistani operative as evidence.
An examination of the officer's WhatsApp data allegedly revealed an extensive exchange between the two.
According to the charge sheet, the communication included:
- 3,008 text messages
- 65 photographs
- 65 reactions
- 42 voice calls
- Four video calls
- Six URLs
The police are continuing to investigate the extent of the classified information allegedly shared and whether additional military personnel or other individuals were involved in the case.
