translated from Spanish: A man is arrested for investigation of the Nantes Cathedral fire

A man is arrested in the investigation open for the possible cause of the fire that occurred on Saturday in the cathedral of Nantes, indicated today the prosecutor of the French city, Pierre Sennes.
The detainee, who is about 30 years old and volunteering for the diocese, had to shut down the cathedral on Friday night, the broadcaster “France Info” said.
He is under arrest from Saturday at noon and police want to clarify inconsistencies in the explanations he has given about his employment and how he closed the basilica.
Sennes insisted on being cautious and pointing out that it is premature to draw conclusions from this element of the investigation.
The prosecutor decided to open a voluntary fire investigation because firefighters arriving at St. Peter and Paul Cathedral alerted by people who saw the building in flames encountered three different fire bulbs, one on the organ and two others on the ship.
From the first investigations performed, no signs of forcing access have been found.
Firefighters managed to control the fire within a few hours, which although it has not endangered the structural elements of the cathedral, completely charred the large organ and caused irreparable damage to some other elements, such as a painting by the 19th-century painter Hippolyte Flandrin.
