TUNIS (AP) — The publisher of the Tunisian newspaper Attounissia and two of its editors were arrested Wednesday on charges of violating public morals for publishing a nude photograph.

In the photograph, Sami Khedira, a German-Tunisian soccer star who plays for Real Madrid, is dressed in a dinner jacket with his hands covering the breasts of his otherwise naked girlfriend, Lena Gercke, a German model.

Chokri Nafti, a spokesman for the Ministry of Justice, said the prosecutor of the republic ordered the detention of the newspaper’s publisher, Nasreddine Ben Said; the editor in chief, Hbib Guizani; and the editor of the world section, Hedi Hidhri, pending the investigation.

They were charged with an assault on public morality.

A journalist at the newspaper said it had received telephone calls threatening to burn down the premises. The building is now guarded by the police.
