A couple’s antics have been exposed on social media after getting overly affectionate on a train.

They were photographed in a compromising position at around 8.45am yesterday.

The woman was seen straddling her boyfriend as he sat in one of the seats, to the alarm of some passengers, who took to Facebook to complain about their behaviour.

Witnesses said the couple later got off the train at Chatham.

British Transport Police and Kent Police said they had not received any complaints.
