As the political upheaval in Kiev gets uglier and uglier, a video has emerged of riot police making a detained protestor strip and stand naked in the snow while they photograph him.

To add to the unsavoury nature of this already blatantly malicious act, temperatures in Kiev dropped to -10 Celsius that day.

“A photo for the memory books,” said the photographer, as the officers forced him to hold a frigid piece of metal tubing.

Three protesters have been killed and more than 150 police have been wounded after several days of violent clashes in the centre of Kiev.

Ukrainian President Viktor Yanukovich has called for an emergency session of parliament to end the violent unrest.
