Charity Easter Hunt Hit By Missing Giant Egg Mystery

Two giant eggs which went on display as part of a charity Easter egg hunt have gone missing, a charity said today.

The Post Box Egg, designed by Benjamin Shine, and Natasha Law's egg called Hatch were two of 200 placed across London to raise money for the Action for Children and Elephant Family charities.

But the organisers of the Faberge Big Egg Hunt say that the eggs, which were due to be auctioned on March 20, have disappeared.

A spokesman said: "We are all devastated. Benjamin's post box egg was already a firm favourite with children and families taking part in the hunt.

"We appeal to whoever took the eggs to return them so they can continue to delight London and help raise vital funds for two charities who have worked so hard to put this on.

"The eggs can be returned to 104-108 Curtain Road, London or call 020 3124 0661.

"We are putting on extra security for all the eggs, and ensuring that they are safe, so people can continue to enjoy them and take part in the hunt.

"We really appreciate everyone's support and concern. The hunt, the fun and the fundraising goes on, so please do get out there and enjoy it."

The Faberge Big Egg Hunt aims to raise £2 million for the two charities with the giant eggs having been created by some of the world's leading artists and designers including Mulberry, Sir Ridley Scott, Zandra Rhodes, Diane Von Furstenberg, Marc Quinn, Bruce Oldfield, the Chapman Brothers, Theo Fennell, William Curley, Candy and Candy, Zaha Hadid, Bompas and Parr and Polly Morgan.

The event is also hoping to break two Guinness World Records for the most participants in an Easter egg hunt and the world's most expensive non-jewelled chocolate egg sold at auction, as designed by William Curley.
