SVT's editorial staff in Norrköping, which is manned in the evening, was evacuated following a threat to the business. The evacuation also hit Sweden's Radio which is in the same building.

"We have been to the sites without finding anything," says Monica Bergström, spokesperson for the police in the East region.

The evacuation lasted for 30 minutes and did not affect the broadcasting operations.

- We received an e-mail threat and connected our security department, says Anna-Karin Thorstensson, editor-in-chief of SVT Nyheter Öst.

- Due to the prevailing situation in our security area, the security department chose to engage the police.
