Early morning travelers on Berlin's subway got the shock of their life as they saw a couple having sex in a empty train station.
One passenger quick enough grabbed his mobile phone and filmed the randy couple’s early hour adventure, which has gone viral on the internet.
When the man spotted the train and realised the pair were being filmed, he raised his middle finger at the cameraman, while continuing his sex act in full flow.
Footage from the Schoenleinstrasse underground station shows the woman leaning against the wall with her skirt raised.
Clothing choices suggest that the eager pair had attended a social event earlier that night, with the man donning a tuxedo and woman a smart, Mirror.com.uk reported.
Transport officials refused to comment
Media parties in Germany are searching for the couple and have offered a reward for the identity of the pair.
At the time of the report the video had over 182,000 views
