PARIS—A 39-year-old man has been arrested in connection with a fire in the 15th century cathedral in the French city of Nantes that blew out stained glass windows and destroyed the grand organ, TV channel LCI reported on Sunday.
The man, a Rwandan refugee, worked as a volunteer for the cathedral and had been in charge of locking up the building on Friday night, LCI said, citing prosecutor Pierre Sennes.
