The woman did not know the man from before. Footage from surveillance cameras shows him standing at the entrance to the toilets, waiting. When the woman started walking down the stairs, he followed. After her visit to the toilet, she was forced back into the toilet and subjected to the assault.
Another man heard screams for help and tried to catch the perpetrator, who ran away.
The 22-year-old denies the crime, but is sentenced to three years and three months in prison and deportation.
