Giuseppe Pinelli was an Italian anarchist arrested by police in Milan. A few days later he was seen falling out of the police station window. It is still not clear exactly what happened to Pinelli. Right-wing activists were later convicted of carrying out the bombing for which he'd been arrested. His story was turned into a popular play by the Italian dramatist Dario Fo. Anna O'Neill has been speaking to Silvia and Claudia Pinelli about their father, and their continued search for the truth.
