Publisher Scholastic has halted publication of a book by children's author Dav Pilkey, best known for his Captain Underpants series, who offered an online apology for the title's unintended "racist imagery".

Pilkey, author of more than 40 books, said The Adventures Of Ook And Gluk: Kung-Fu Cavemen From The Future, first published in 2010, would be pulled from retail and library shelves.
