Five members of a Hong Kong union behind a series of children's books about sheep trying to hold back wolves from their village have been arrested for sedition, police announced.
The arrests by the new national security police unit, which is spearheading a sweeping crackdown on dissent, are the latest action against pro-democracy activists since huge and often violent protests convulsed the city two years ago.
Police said the two men and three women aged between 25 to 28 "conspired to publish, distribute, exhibit or copy seditious publications".
The group was attempting to stir up "the public's -- and especially young children's -- hatred towards Hong Kong's government and judiciary and to incite violence and illegal acts," police said in their statement.
The five arrested people were members of a union and HK$160,000 ($20,600) in funds had been frozen under a new national security law China imposed on Hong Kong last year, police added.
A police source told AFP that the arrested men and women were members of The General Union of Hong Kong Speech Therapists.
