Videos of couples getting 'intimate' on metro cause stir in India
Passengers urged to behave and show 'decorum' as videos of couples appear online

Passengers using the metro in New Delhi have been told to maintain "decorum" and "etiquette" after hundreds of videos showing couples engaged in what is locally known as "intimacy" surfaced online.
Many of the videos appear to use footage leaked from the metro's own CCTV system. Others appeared to show sexual acts in stairwells or passageways.
Security staff have denied leaking the videos and say most were filmed on handheld cameras.
The Hindustan Times said about 250 clips had been edited together and were available for viewing on pornographic websites. Other reports suggest the number is much lower.
"We have found two such clips on the internet showing couples getting intimate and sent them to the cybercrime cell. We will also seek help from the Central Industrial Security Force to unearth the reality," metro spokesman Anuj Dayal said.
