Pope gunman's Italy visa not valid: cops

Mehmet Ali Agca, the Turk who attempted to assassinate John Paul II, has been ordered out of Italy two days after he paid a surprise visit to the late pope's tomb.

The 56-year-old former political extremist has been in custody since Saturday, when police realised he had entered the country without the appropriate visa.

He was expected to be put on a plane out of the country on Monday after a magistrate rejected an appeal for him to be detained and questioned in connection with an unresolved investigation into the 1983 disappearance of a 15-year-old schoolgirl, Emanuela Orlandi.

While serving time in an Italian prison for his 1981 assassination attempt on the late Polish pope, Agca claimed in an interview that Orlandi, a Vatican citizen, had been kidnapped by Bulgarian agents from the same Grey Wolves movement of which he was a member.

He never provided any evidence to support his claim and the case was closed in July 1997.

Agca's visit to the Vatican on Saturday came 31 years to the day after John Paul visited him in prison in Rome to forgive him for the 1981 shooting that nearly killed the leader of the world's Catholics.

Then 23, he shot the pontiff twice from close range in St Peter's Square, one bullet passing through his abdomen and another narrowly missing his heart.

Vatican police agreed to let him lay white roses on the late pope's tomb but his request for a meeting with current Pope Francis was rebuffed by officials who have made no secret that they regard the former gunman as a slightly deranged publicity seeker.

Agca, who now professes to be a devout Catholic, served nearly three decades in prisons in Italy and Turkey for the papal assassination attempt and other crimes including the murder of a journalist.
