This was how it went:

Designers were showcasing creations from their Spring/Summer 2014 Men's collection at the Dolce & Gabbana catwalk show when a streaker leapt onto the catwalk and ran up and down in full view of the city's fashion royalty (as seen in the video)

He just invaded the spotlight and disrobed entirely but for a pair of red trainers.

Andso, security men ran after him but he pulled a succession of bizarre, gurn-like expressions as he skipped back and forth along the catwalk attempting to avoid them all.

Stars including Barcelona striker Lionel Messi were stunned...others simply gasped.

Audacity or madness, what do you call it?
