Restrictions lifted at Swedish nuclear plant after bomb threat

A nuclear power plant north of Stockholm was partially evacuated because of a bomb threat Wednesday but police later lifted restrictions in the area after no explosives were found.

Bomb-sniffing dogs would continue to search the Forsmark nuclear plant on Thursday, but most of the officers sent to the scene were called back and roadblocks were lifted, police spokesman Christer Nordstrom said.

He would not say how the threat was received or whether police had any suspects, but said investigators were evaluating "interesting information about people who have something to do with the incident."

"We take the threat very seriously because it was directed toward a nuclear power plant, but we only have two patrols there now," he said.

Earlier Wednesday, a spokesman for the Swedish Nuclear Power Inspectorate said some staff who were not essential to the energy production at the plant were evacuated. The reactors remained online.

Forsmark, located about 100 kilometers (60 miles) north of Stockholm, had drawn criticism recently after reports of flaws in its safety controls. Its chief executive resigned in February, days after two of its three reactors were shut down because of possible technical problems.
