THREE first edition Harry Potter books, worth around £560, were stolen during a break-in at an Isle of Wight charity shop.
Thieves smashed the front window of Feather Friends Rescue, Pyle Street, Newport, on Sunday, and grabbed the valuable books.
Their haul included two copies of The Prisoner of Azkaban, worth £154 each, and a copy of The Deathly Hallows, worth around £250.
They also stole a signed copy of James Herbert's thriller, Portent, worth an estimated £36.
Sam Morley, who founded Feather Friends Rescue to care for injured and unwanted birds, said she was disgusted someone would steal from a charity shop.
"I just think they are the most low-life people. To steal from a charity shop, from volunteers who give their time to help animals. Those books were donated by a lady from Totland to help us build an aviary for parrots," said Sam, 44.
"The window is made of toughened glass and they were only able to make a small hole in it. They must have been there a while so it's possible someone saw something. Hopefully the whole thing has been caught on CCTV."
She urged witnesses to contact the police and has offered a reward to anyone who came forward with information leading to a conviction.
The break-in happened between 2pm and 10.30pm.
