Owner of The Entertainer toy shop, Gary Grant, said putting 2000 of Frozen's Elsa Snow Glow dolls on their website caused it to crash twice in the busiest day the site has seen.

The Snow Glow Elsa doll has become such a sensation that five more factories have been enlisted in China to help meet the demand, and one Dublin toy shop had to call the police as parents queued for the dolls.

Mr Grant said he is restricting the dolls to "one per person" due to parents being "overcharged on ebay" for this year's number one selling Christmas toy.

Mother, Sandra Phelan, who is trying to get hold of a Snow Glow Elsa doll for her two and a half year old daughter said she didn't expect "this much pressure" and it is "very difficult to get your hands on it".

The toy's manufacturer, Jakks, said of the doll's availability: "We are working with our retail partners to supply our most popular frozen dolls on a weekly basis. Due to the high demand the dolls are selling through as soon as they hit the shelves.”
