A world record attempt to make the largest human star formation, which took place in a Watford gym, has been officially recognised.

Guinness World Record officials confirmed that the 365-person shape formed at the Watford Leisure Centre in Woodside last month was the largest ever recorded.

The previous record stood at 326 people in America.

Staff at the centre managed to smash the previous milestone by recruiting gym-goers and willing residents from the surrounding area for the attempt, which took place on December 12.
