"In BROAD DAY LIGHT!" was one person's incredulous response.

"At 7 in the damn morning," said another.

The video shows the man and woman getting busy against the wall of the platform, making no attempt to be discreet.

But now a spokesperson for British Transport Police has confirmed that they are looking into the brazen alleged sex act.

"We are investigating reports of a couple engaging in sexual activity on a platform at Hackney Downs station," said BTP.
