A Tunisian rapper who went on the run after receiving a 21-month jail sentence in absentia in August for songs deemed insulting to police was jailed for four months at a retrial Thursday. Weld El 15, whose real name is Alaa Yacoubi, had surrendered to the authorities at the courthouse for the retrial. The court found him guilty of affront to public decency and insulting behaviour towards public servants in his songs, and ordered him taken straight to the cells to serve his sentence.
