Rached Ghannouchi, Tunisia's former parliament speaker, appeared before an investigative judge on Tuesday to be questioned on suspicion of incitement against the police, which he and his Ennahda party deny.
Ghannouchi's lawyer said the accusation was based on a complaint by police about a speech he gave last year at the funeral of a party member, saying the deceased "did not fear a ruler or a tyrant, he only feared God".
