(CNN)Shin Dong-hyuk's horrific descriptions of his time in a North Korean prison camp became a best-selling book, made him a key witness before the United Nations and grabbed headlines around the world.

He was one of the most high-profile North Korean defectors, winning several human rights awards and inspiring a documentary as his memoir was translated into 27 languages.

Now the publisher of the book and its author say Shin -- who claims to have been born in and escaped from a North Korean prison camp -- has revealed that parts of the story he told weren't true. Shin may have spent most of his life in North Korea at a different prison camp, rather than the total control zone that formed the title of his biography.

Shin's accounts of his time in the gulag have been widely reported in interviews with media including CNN. He also wrote an opinion piece describing his experiences for CNN Digital.

Blaine Harden, author of the book "Escape from Camp 14," said in a statement on his website over the weekend that Shin had changed "key parts of his story."

"On Friday, Jan. 16, I learned that Shin Dong-hyuk, the North Korean prison camp survivor who is the subject of 'Escape from Camp 14,' had told friends an account of his life that differed substantially from my book," Harden said. "I contacted Shin, pressing him to detail the changes and explain why he had misled me."
