Princess Hassa bint Salman Al Saud was sentenced to ten months suspended and fined € 10,000 ($ 11,000) by a French court on Thursday.
She was convicted in the absence and found guilty of armed violence and participation to hold someone against their will. Her bodyguard received an eight-month suspended sentence and was ordered to pay a fine of € 5,000 ($ 5,600).
Emmanuel Moyne, a lawyer for Hassa, told CNN: "It is with great disbelief and indignation that we received … this verdict."
Moyne added that he would appeal the decision and prove that The princess is "completely innocent of the accusations made against her."
Eid previously said he worked in a bathroom in the apartment on Paris's exclusive Avenue Foch – owned by Saudi Arabia's King Salman bin Abdulaziz Al Saud – and took photographs of the furniture "for reference "when he noticed the princess's reflection in the mirror.
According to Eid's story read in court in July, when the princess saw him, she allegedly ordered her bodyguard Rani Saidi to take her phone. Eid claimed that Saidi then handled him and kicked him in the face.
Eid claimed that the princess then insulted him and said, "You are like, damn, dogs. You see how to talk to a princess, how to talk to the royal family."
He said Saidi put a gun on the back of his head and gave him two choices: "Kiss the princess's feet or risk another attack."
Eid once complained to police he was released from the apartment. The police interrogated the princess for two hours and then released her. Three days later she left the country.
An investigating judge tried to contact the princess several times but was unable to reach her and finally issued an international arrest warrant for her in 2017.
