New Delhi, Apr 15 (IANS): In a bizarre incident that left the Delhi Metro red-faced and its commuters shocked, a hardcore pornographic clip played out on a giant screen at its busiest Rajiv Chowk metro station in the heart of the national capital.

With a video of the giant screen playing the explicit clip going viral on Saturday, the Delhi Metro Rail Corporation (DMRC) claimed being "unaware" about the clip and put the onus on a private contractor entrusted with installing the screen meant for displaying advertisements.

The 25 second video widely shared on social networks, shows the clip being played on the screen with commuters passing by the screen in usual hurry but some of then stopped to record it on their mobile phones.

"The DMRC is not aware about this clip. However, this LED screen was under commissioning and testing by a private contractor and the same is still under commissioning. The work is still not completed," Delhi Metro spokesperson Anuj Dayal said in a statement.

"We will check all the details of the testing and commissioning process of the contractor to establish whether any such clip was played and take adequate safeguards and action," he said.

While there have been contrasting reports of the day of the incident, some claiming it happened on April 9, the DMRC official refused to clarify about that.

The incident has attracted hilarious reactions on Twitter with some targeting Delhi Chief Minister Arvind Kejriwal and others Prime Minister Narendra Modi.

"Shri Kejriwal said 'As a IIT Engineer I can tell you 10 ways hack EVM'. He Proved it by hacking Rajiv Chowk station & Played his fav video," posted a user.

"Porn clip played on screens at Rajiv Chowk. Now if THIS doesn't get Delhiites to use public transport, nothing will," said another.

"The video at rajiv chowk is nothing but personification of what Modi is doing to India," twitted a user.

A similar incident took place at a bus stand in Kerela's Wayanad district in June 2015.
