CALABRIA, Italy, Jan. 31 (UPI) -- Three Moroccans, one a Muslim cleric, were arrested in Italy on suspicion of training recruits for international terrorism, Italian police said.

The imam of Sellia Marina and his son were arrested at their home in Calabria Monday and the third person arrested is part of the Moroccan community of Lamezia Terme, ANSA reported.

Authorities also searched the homes of nine other people, arresting one for possession of marijuana. The arrests stemmed from a "complex" investigation by security police and Italy's postal police, the report said.

Investigators said the men used the Internet to receive and send "multimedia documents about arms and explosives training" and possessed software that "could be used to sabotage computer systems."
