SHOPPERS were left pleasantly stunned after a dancing flash mob broke out on the streets of Colchester to celebrate World Down's Syndrome Day. 

Members of Project 21 congregated in two prime Colchester locations to spread awareness for the charity and the work it does. 

Castle Park and Culver Square were taken over by a 50-strong flash mob, whose members all danced for ten minutes.

The dancers cut shapes to a mash-up of songs including a remix of I Am What I Am by Gloria Taylor and Never Gonna Not Dance Again by P!nk. 

Once the two performances burst into life, a congregation of onlookers gathering, filming and enjoying the wonderful choreography.

Every year the charity conducts a flash mob in one of the locations some of its members reside in. 

With collection buckets, the dance managed to raise £225 which will all be put towards the charity's minibus fund.

Alex Munn, the founder of Project 21, said: "Each year we surprise the public with a flash mob to celebrate World Down's Syndrome Day.

"We chose Colchester this year to celebrate this wonderful community where many of our members reside.

"The flash mobs raise awareness and showcase the talent of our members with Down's Syndrome. They're always really special days and it's great to get the local community involved too."

Alex, 31, added: "I started Project 21 just over five years ago to change the lives of people with Down's Syndrome and give them access to better opportunities and experiences."

In previous years, the flash mob has taken over the streets of Trafalgar Square and Cambridgeshire.

World Down's Syndrome Day aims to create a single global voice advocating for the rights, inclusion and well-being of people with Down's Syndrome.

This year's theme for World Down's Syndrome Day was 'End The Stereotypes', aiming to spread the message which not all people with Down's Syndrome are the same and all of them act differently and like different things.
