The 39-year-old Rwandan refugee was Saturday arrested by French police as part of an investigation into a series of fires that have gutted the Cathedral of St. Pierre and St. Paul in the western French city of Nantes.
The fires, according to French prosecution, are believed to have been started deliberately.
According to the Europe1 news outlet, the Rwandan Man was picked from home on Saturday afternoon and the prosecutor revealed that he was in custody on Sunday morning.
The man worked as a volunteer for the cathedral and had been in charge of locking up the building on Friday night, local media said, citing prosecutor Pierre Sennes.
Sennes said the man in custody was being held to clear up inconsistencies in his schedule.
The individual is said to have been working for the diocese as a volunteer though he was not previously known to police.
On Saturday, prosecutor Pierre Sennes revealed that three fires had been started at the church. The blazes completely destroyed the cathedral’s grand organ, smashed a prominent stained glass window on the building’s facade, and ravaged a valuable 19th-century painting that had been sent from Rome.
