Regeni Cambridge teachers don't answer

(ANSA) - Rome, June 7 - The Cambridge University teachers supervising Giulio Regeni, the Italian student tortured and murdered in Cairo, declined to answer Italian prosecutors' questions on emails about his work on Egyptian trade unions, judicial sources said Tuesday.
    Regeni's tutor Maha Abdelrahman and others availed themselves of the option of not answering questions from Rome assistant prosecutor Sergio Colaiocco and security police, the sources said.
    Prosecutors had been hoping the emails might shed light on Regeni's contacts and work with the trade union movement, which some think may have been linked to his murder.
