What did Italy know and when did they know it?

A Turkish newspaper is claiming that the Italy was warned of Mehmet Ali Agca's plans to assassinate Pope John Paul II a year before the incident took place. In looking over the article, it's unclear how seriously Italy should have taken the threat - especially as over one hundred countries were warned.

He explains how they foresaw that he would attempt to assassinate the Pope and warned the countries by issuing a red bulletin as follows. "After murdering Abdi Ipekci, he escaped from the prison where he was sentenced life. We informed all the countries about his arrestment and extradition to Turkey. We printed his photo, provided them with his description and fingerprints. We explained the modus operandi of the incident as well. We noted in the red bulletin that 'he said he would kill the Pope". We reported this not only with a red bulletin but also with a general wireless circulation."

It's also not noted in the article what actions the Italian goverment took or whether Turkey informed the Vatican directly about the threat.
