Italian authorities deported a 37-year-old Tunisian on Friday who alleged tried to convert fellow inmates to radical Islam while he was in jail for minor offences, the interior ministry said in a statement.
The unnamed Tunisian was deported aboard a flight to his native Tunisia from Rome's Fiumicino airport, the ministry said.
A total of 131 suspected Islamist extremists have now been deported from Italy since January 2015, 65 of them this year, said the ministry.
Earlier on Friday, police in Milan shot dead a 24-year-old Tunisian fugitive, Anis Amir, who was suspected of driving a truck laden with steel into a popular Christmas market in Berlin, killing 12 people and injuring 53.
The Berlin attacks was claimed by the Islamic State jihadist group.
Amir, an IS supporter, first entered Italy by boat in 2011 spent four years in Sicilian jails for arson, assault, intimidation and embezzlement. After his release in 2015, he was ordered to leave Italy and entered Germany a few months later.
He had been due to be deported from Germany after his application for asylum there was rejected.
