Rare books worth tens of thousands are among the items stolen in a burglary in Thetford.

Police say an address in Napier Place was broken into between 11.50pm on Monday, January 8 and 1.30am the following day when two men forced their way in.

Items stolen include a hardcover Bloomsbury first edition of J.K. Rowling's Harry Potter and the Philosopher's Stone in a red custom box worth around £40,000.

A hardcover signed first edition of Colour of Magic by Terry Pratchett worth around £9,000.

A set of four first editions of Winnie the Pooh in a black custom box worth around £5,000.

A hardcover first edition of The Hobbit from 1937 worth around £7,000.

A first impression of The Great Gatsby from 1925 in a dark blue custom case worth around £2,000.

A paperback copy of Brief History of Time from 1983 with a thumbprint signature by Stephen Hawking.

Two first editions of the Gunslinger by Stephen King worth around £2,000 each.

A sketchbook from the 1820s-1840s by an unknown artist including pencil and water colour sketches.

PC Gideon Weigelt-Holmes, of Thetford Police, said: 'These books are very rare and in some cases unique and not the sort of thing you see every day.

'I am urging people, especially book dealers or those working in specialist book shops to be vigilant in case they are offered for sale.'

Anyone with information should contact PC Weigelt-Holmes at Thetford police on 101.
