BJP today filed a complaint against a journalist for posting a morphed picture on social media that showed Prime Minister Narendra Modi bowing to touch the feet of Saudi Arabia's King Salman even as the government said it is looking into the matter.

Arvind Gupta, the party's technology cell in-charge, filed a complaint with the Cyber Cell of Delhi Police against the person working with a private TV channel for "tweeting morphed images of PM Modi".

"We have filed a complaint. The Cyber Cell will take due action in this regard," he told PTI.

The journalist, who later expressed regret for the "error", had posted a picture in which the Prime Minister is seen bowing before a Saudi leader. Modi returned from a visit to Saudi Arabia past last midnight.
