Melbourne was treated to some beautiful sun last weekend, but for these Melburnians, they got a little moon as well.

Onlookers on Sunday afternoon were stunned when they saw a man swimming around in the Yarra River… naked.

It’s said the man stripped off and jumped into the murky waters from Princes Bridge in Southbank.

Police were called to the scene around 4.15pm and took the man, believed to be in his 40’s and from Torquay into the hospital to be treated for minor injuries.

It’s also believed he was intoxicated at the time of the incident and is expected to be charged for drunk and disorderly behaviour, and obscene exposure.
