New Delhi: A young couple travelling on the Kolkata Metro were reportedly harassed and thrashed by some of their co-passengers for being allegedly too vulgar by getting too close to each other at public place. They boarded a train late on Monday night.

It all began after some elderly co-passengers objected to their "intimacy in public", leading to a heated argument. The young couple was reportedly bombarded with embarrassing questions followed by punches, kicks and slaps inside a station once they deboarded the train.

"Unfortunately, no complaint has been lodged as yet and this makes it very difficult to conduct an inquiry," Kolkata Metro Railway CPRO Indrani Banerjee said, adding that the Metro was "against moral policing".

The CCTV footage in the station did not record any incident of an assault, she claimed, though videos of the thrashing, which were shot by eyewitnesses, have since gone viral all over the social media.

“Unfortunately there has been no complaint lodged as yet and this makes it very difficult to conduct an inquiry. Had there been some sort of a complaint from somebody, we could have proceeded,” Kolkata Metro Railway CPRO Indrani Banerjee said. “It is becoming very difficult to get to the bottom of the incident,” she added.

Asked how they would handle the protests being staged outside Dumdum Metro Station, she said: “I have just come to know about the protest. People are well within their rights to register their protest but this should not disrupt our services in any manner.” She also said that the metro railway is “against moral policing”.

Protests were held outside the Dum Dum Metrostation on Tuesday against the incident. "A young couple embraced in Kolkata Metro. It made a bunch of frustrated old losers angry. They beat them up. Scenes of hatred are allowed. Scenes of love are considered obscene," writer TasleemaNasreentweeted
