The son-in-law of Tunisia's deposed dictator returned from exile to face outstanding cases against him and was sentenced to six months in prison on gun possession charges.

After the verdict was pronounced late Tuesday, Slim Chiboub was taken to Mornag prison, according to his lawyer Wissam Saidi.

The judge also ordered him jailed while a case of influence-peddling is considered over accusations he received kickbacks in a deal with French industrial group Alstom.

Chiboub, a businessman and football club owner, fled to the United Arab Emirates after the January 2011 overthrow of his father-in-law, Zine El Abidine Ben Ali.

Chiboub announced recently he would return to Tunisia to face the cases against him.
