Moroccan authorities should drop charges and release a rapper who has spent three weeks in pretrial detention on charges that he insulted the police in his songs and a video set to his music, Human Rights Watch said. Police arrested Mouad Belghouat, known as 'al-Haqed' (the sullen one), on March 29, 2012, because of a YouTube video with a photo of a policeman whose head has been replaced with a donkey’s. The lyrics denounce police corruption.
