A Florida sheriff branded an alleged transgender prostitute as being 'uglier than a mud fence' as he held up their 'before and after' mugshots.

Polk County Sheriff Grady Judd had been parading the results of a recent crackdown by his Florida department which saw nearly 250 people arrested for alleged human trafficking.

One of those was Jason Balthis, a 43-year-old who Sheriff Judd said was charged with 'offering to commit' as part of the 'Fool Around and Find Out' crackdown.

Holding a picture of Balthis as a woman up, he said: 'This Jason Balthis, when he walks in you think "well I have set up a deal with an ugly woman", and I think you'd all agree he's an ugly woman.'

He then held up a mugshot of Balthis without any makeup on or his wig, showing a bald man with remnants of what appears to be lipstick still on him.
