A Harry Potter villain has donated valuable books to the British Heart Foundation in Keighley.

Braithwaite actor Michael Thompson plays a Death Eater in the latest Harry Potter movie.

He is spending much of this month filming on the set of The Deathly Hallows.

For the past few years Mr Thompson has been collecting first editions of the famous books written by JK Rowling.

Now he has given a full set of seven books to the BHF’s charity shop in Keighley.

They are being valued by BHF experts in Halifax and are likely to be auctioned on ebay.

Mr Thompson said one of the books had previously been valued at about £100.

It is notable for a picture of Harry’s headmaster, Professor Dumbledore, very different to his film appearance.

The magician is pictured on the back of the book as a young man smoking a pipe.

Mr Thompson decided to donate books after his mother, Noreen, was fitted with a pacemaker for her heart.

He has about 60 Harry Potter books at home but admits that even after taking part in filming, he has never read any of the stories.

Mr Thompson has appeared as an extra in several films and TV shows like Casualty and Emmerdale.

He had a small part in Coronation Street and recently filmed scenes as a taxi driver in Eastenders.

He is one of about 20 Death Eaters — henchmen of Potter’s nemesis Voldemort — appearing in The Deathly Hallows. Mr Thompson’s stint ends next month but filming will continue until next June. The film will be released in cinemas in two separate parts.
