Naked Gay couple caught on camera having SEX in front of horrified families on a platform at Melbourne Train Station (Details, pics)

Two men were caught on camera appearing to have sex on the platform of a busy train station in Melbourne.

Passengers at Flinders Street Station were horrified when the pair stripped naked in front of them before dancing around a stolen pot plant and getting intimate.

Video taken of the bizarre incident about 11pm on Saturday appeared to show one of the men standing close behind the other and rubbing up against him.

The other appeared to reach around to fondle his bare behind before they separated and began to put their clothes back on. Both men, aged 22 and 25, were later arrested and were charged with wilful and obscene exposure and theft.

Police told the Herald Sun they were allegedly seen naked on the platform and stole two pot plants from outside Melbourne Town Hall.

Samantha Lenkic said she witnessed the pair along with dozens of people on the platforms, including an elderly woman who yelled at them.

'I've never seen anything like it, I was stunned... it was quite gross and not clearly something I want to see,' she said.

'Others were shocked, some people were laughing watching it all unfold.'
