“A very strong odor.

Like a stinking smell of sulfur and eggs and it was impossible to be in the premises at all".

This is how Daniel Hällgren described the smelly premises to SVT on Monday.

The stench disappeared temporarily after airing the premises and flushing the water trap, but the odor returned during the afternoon.

During Tuesday, however, the rancid smell was not felt and the staff returned to the workplace.

- The stop has been lifted, confirms safety representative Daniel Hällgren to SVT.

What caused the stench is still unclear.
