DANCERS invaded a university campus for an impromptu piece of public dancing.

About 40 students burst into dance outside Huddersfield University’s Creative Arts Building at 1.15pm yesterday in an organised "flash mob."

The dancers shook their legs and ran about wildly as the Hokey Cokey boomed from the university PA system.

Onlookers, caught unaware, starred in slight confusion while others reached for their mobiles to film the bizarre spectacle at the University’s Queensgate campus.

A flash mob is when a large group of people suddenly assemble in a public place, perform an unusual action for a short time, then quickly disperse.

Other flash events, which have taken place in large cities across the world, include mass pillow fights, silent discos and naked bike rides.

The event was organised by the University and a mobile phone company to promote a community feel at Huddersfield University.

Drama student Hannah Bentley, 20, who took part in the mob, said: "It’s a very good way to get yourself back to how you used to be when you were young.

"It does make me feel like going back this afternoon and studying harder."

Co-drama student Joanne Bakewell, 19, added: "That was really fun."

The first flash mob was created in Manhattan in May 2003, by Bill Wasik of Harper’s Magazine.
