A Las Vegas man who's accused of stealing underpants and g-strings from a troupe of strippers from New Zealand and Australia, was faking mental illness at the time.

The 25 year-old has now been declared competent to stand trial over the incident, which happened at the Excalibur Casino on the Vegas strip.

He was arrested after members of the Down Under troupe complained he'd stolen props, a pair of teal underpants and a g-string.
