The smoke development at the Royal Opera in Stockholm ceased without the Rescue Service being able to find an explanation, says the Opera's press officer Jenny Mattson.
We must of course find out where the smoke came from, she says.
When the fire alarm went off on Saturday evening, there was no audience left at the Opera. The smoke came from the top floor where the Opera has its ballet department and costume studio.
During the night, the National Property Board (SFV) has had the building under surveillance and the investigations into the smoke development will continue on Sunday.
SFV is also renovating the roof, but I don't know if it has anything to do with the matter, says Jenny Mattsson.
