"It is still blocked off and the national bomb shelter will investigate the object to rule out that it is not a dangerous object," said Katarina Rusin, press informant at the police.

The discovery happened as it began to burn on a public toilet. Passers-by were quick and able to extinguish the fire.

"That was very advisable," says Katarina Rusin.

In connection with the toilet was found the suspicious object which is now to be investigated.
