A children's book carrying a "picture" of Prophet Muhammad sparked protests from some people here who attacked the publishing house and damaged furniture and computers claiming the art work was an insult to Islam.
According to police, about a dozen people barged into the New Jyothi Publications office last evening, damaged furniture and computers and ransacked files and books, alleging the picture in the book insulted Islam and the Prophet.
The publication house later regretted for the lapse on their part and said the picture, downloaded from the Internet, had inadvertently got into the book and withdrew it.
The book, entitled "Stepping Stones", was brought out as study aid for class-two students for English medium schools.
The controversial picture appeared in a chapter on world religions along with pictures of Buddha, Mahaveer, Jesus Christ and Shankaracharya.
The picture in the book was first noticed when it was distributed in a school in Kasargode district.
Police have registered a case but no arrest has been made.
