Banksy, painted in white paint, was found in good condition in Italy earlier this month after a joint operation by French and Italian police.
Police have made arrests across France as part of a coordinated operation. Two people were investigated for organized theft, while the other four are accused of concealing the theft. All were placed in police custody pending trial.
The work, part of a series made by Banksy during a visit to Paris in 2018, was stolen from the Bataclan in January 2019. Video footage showed hooded thieves crossing the fire door. Detectives announced earlier this month that they had found work on an abandoned farm in the Abruzzo region east of Rome.
The theft caused widespread anger in France. Bataclan said it was “a symbol of remembrance and belongs to everyone: locals, Parisians, citizens of the world”.
In what the then president, François Hollande, described as an “act of war”, terrorists carried out a series of shootings and suicide attacks in the French capital on November 13, 2015. The Islamic State then claimed responsibility.
Last November, French prosecutors announced that 20 suspects would be tried for these attacks, including Salah Abdeslam, suspected of being the only surviving member of the group of armed men and heavily armed bombers. Abdeslam was arrested in Belgium several months later after an international manhunt. He was sentenced to 20 years in prison in Belgium after being found guilty of attempted murder of police during a shootout in Brussels in March 2016. He was then extradited to France.
