The aggrieved officer, a Lieutenant Colonel, is a flight commander of the Bathinda-based 668 Reconnaissance and Observation Squadron. The pictures and videos, along with the officer’s wife’s phone number, appeared on at least 19 porn sites, sources said.

The Commander, 10 Corps Artillery Brigade, an officer of the rank of Brigadier, is conducting the Court of Inquiry in Bathinda. Military Intelligence has intervened to get the sites blocked. The Commanding Officer of the unit has been moved out.

The Army is investigating how the explicit pictures and videos were taken, and how the Major — who serves in the same unit — got hold of them. The role of the other officers in the unit is also under scrutiny, as is the possibility of the incident being part of a larger racket.

The longest of the over half-dozen videos uploaded on the Internet is of three minutes, 50 seconds’ duration, the sources said.

Following repeated attempts at getting a comment, Army Headquarters spokesperson Colonel Jagdish Dahiya said, “There are charges of infringement of privacy, which are being inquired into. Any further details cannot be divulged at this stage.”

This is the first incident of its kind in recent years in which an officer and his wife are involved; it is also the first instance of explicit content being allegedly uploaded on porn sites by an officer.

In September last year, two Lieutenant Colonels, a Major and a Lieutenant then posted at Western Command faced a Court of Inquiry after a woman Lieutenant alleged assault on her at a superior officer’s residence in the Chandimandir cantonment.
