An armed robber dressed as Father Christmas climbed through the window of a drive-through KFC restaurant on Saturday and demanded cash.

Police are appealing for witnesses to the theft at the restaurant in Hockley Way, Alfreton, Derbyshire.

Officers said the man, described as 1.78 metres (5ft 10in) tall and stocky, climbed through the window at around 10.30pm carrying a knife.

He threatened staff and demanded money before fleeing.

Derbyshire police said the man was wearing a red hat, red trousers and a red jacket over a black top and had his face covered.

Anyone with information was asked to call police on 101.
