Tunisia seeks extradition of Ben Ali brother-in-law from France
The justice ministry, in a statement received by AFP, said it had learned from the Interpol office in Tunis that Belhassen Trabelsi was arrested on Thursday in France.
It said he was facing 17 arrest warrants in Tunisia and 43 international warrants.
There was no official confirmation in France of Trabelsi's arrest.
But a source close to the investigation said he had been detained in the south of the country earlier this week in connection with alleged financial wrongdoing. There were no further details.
The millionaire businessman and brother of Ben Ali's wife Leila Trabelsi left Tunisia in January 2011 when the Arab Spring uprising forced the veteran leader to flee to Saudi Arabia.
Trabelsi and his family flew in a private jet to Montreal where he requested political asylum but Canada turned down his appeal in 2015, and a year later as it prepared to deport him he vanished.
He is wanted in Tunisia where he is thought to have headed a clan that embezzled government funds.
A leaked June 2008 US diplomatic cable concluded that Trabelsi was "the most notorious (Ben Ali) family member and is rumoured to have been involved in a wide-range of corrupt schemes".
Trabelsi - whose holdings included an airline and hotels - has denied the allegations against him, saying he accumulated his wealth from being a successful entrepreneur.
The former Tunisian leader fled to Jeddah in 2011 with his second wife Leila Trabelsi and children Mohamed and Halima after a wave of popular protests which inspired the Arab spring revolts that subsequently shook the region.
Since fleeing, they have been convicted in absentia in several cases by Tunisian courts, mostly for corruption.
Ben Ali was also sentenced to life imprisonment for the crackdown on demonstrations during the 2011 revolution, in which 338 people were killed.
Since the 2011 uprising, Tunisia has been held up by Western partners as a model of democracy for the region.
Economic progress has lagged, though, and corruption remains a major problem in the North African state.
