Several locations in the northern counties of Västerbotten and Norrbotten were sealed off Monday while police investigated packages containing white powder, and in the evening, the tabloid Expressen reported that yet another envelope containing white powder had been delivered to the police in Helsingborg, in southern Sweden.
Fredrik Jeppsson with the police in Umeå, told TT this evening that the powder at the postal sorting center there had been identified as a substance that was not dangerous. A bit later, the powder that had been received in Gällivare was also determined to be not dangerous.
Earlier today in Northern Sweden, a letting company in Gällivare and a postal sorting office in Umeå were evacuated, because of packages containing white powder.
About 50 people were examined too see if they had been exposed to any harmful substance.
The disruption to the postal service meant around 10,000 northern households did not get their mail Monday, according to TT.
The package that later came to the Helsingborg police was brought by a man who said he'd received it from a stranger, reports Expressen. A police bomb squad picked up the package to send it to Stockholm for analysis.
The police are now working with the theory that there is a connection between these incidents, and last week's, when white powder was also sent to agencies and government offices.
