Police originally arrested the Frenchman on charges of paedophilia, "setting up a criminal organisation" and "illegal residency" in the kingdom.
, a court handed the accused a 12-year jail term, police sources said, confirming reports in the Arabic-language dailies Akhbar al-Yaoum and Al-Massae.
He also received a fine of 60,000 dirhams ($7,000) to be paid to the family of the girl whose complaint lead to his arrest.
Akhbar al-Yaoum reported that he had confessed to the charges, but police sources said that the accused had appealed the verdict.
The police sources added that the French national had come to live in Morocco four years ago, fleeing the possibility of prosecution for paedophilia at home.
After he arrived in Morocco, he started relationships with two young women he employed as domestic workers, before asking them to help him meet 10-year-old girls.
The two young women were also jailed for eight months for "complicity in forming a criminal organisation".
Thousands of people marched in Casablanca on May 5th to protest against child sexual abuse after a harrowing assault last month in the northwestern Sidi Kacem region nearly killed a young girl.
