New Delhi, June 12: A porn video shown at a high-level meeting has shamed the Border Security Force five months after a jawan's social media video on poor living conditions had left it red-faced.

A deputy commandant of the paramilitary force was making a power-point presentation before senior officers, including eight women officers, yesterday afternoon when he accidentally played the porn clip for 90 seconds, sources said.

An inquiry has been ordered to find out "whether the officer had stored the porn clip on his laptop and accidentally activated the file, or whether someone had played mischief", a Union home ministry official said.

He said the deputy commandant had not been subjected to any preliminary suspension or reprimand, and that any action would be taken after the probe report arrived.

"Mukul Goel, inspector-general (Punjab frontier), will head the inquiry. Stringent action will be taken against the deputy commandant if found guilty," a senior official at the BSF headquarters in Delhi said.

He said the BSF rulebook did not mention any penalty for such an unprecedented "act of gross indiscipline".

Prima facie, sources said, it seemed the deputy commandant had watched and stored the porn clip on his official laptop before using it to make the presentation.

"After attaching his laptop to a projector, he may have unwittingly clicked on a multi-media file where he had stored the porn clip," the BSF official said.

In January, Havildar Tej Bahadur Yadav of the BSF had posted a video alleging the jawans were served very poor food - apparently because their seniors stole their rations. An inquiry found Yadav guilty of indiscipline and he was sacked.

Ironically, yesterday's meeting at the 77 Battalion headquarters in Punjab's Ferozpur sector had been called to discuss the problems faced by jawans posted along the Pakistan border.

The power-point presentation was meant to suggest solutions and to show a documentary on how the jawans were being trained.

BSF director-general K.K. Sharma has been asked to send a report on the fiasco to the Union home ministry, under which the border force functions.

"This is serious. An officer's laptop should not have had a porn clip," a ministry official said.

In April, one of the LED screens at Delhi's busy Rajiv Chowk Metro station, meant to display ads or information, had played a porn video, triggering an outcry and prompting the Delhi Metro Rail Corporation to order an inquiry.

Its report has been handed over to Delhi police, who are still investigating the matter.
