Girls as young as 10 have been victims of the attackers, who are still on the loose, and police are warning females not to go outside alone at night. The 14 separate incidents have all been reported in the town of Ostersund, which has a population of 44,300. While police have refused to release descriptions of the attackers, victims have described the men as of foreign origin. The council, following discussions with police, have now said Earth Hour, a worldwide environmental event involving lights being turned off for 60 minutes, will be cancelled.

Social Democrat spokesman for the council, Ann-Sofie Andersson, said: “Earth Hour is a good and important event, but this year we chose to have the street lights on in view of what has happened. We want everyone to feel safe.” Chief Constable Stephen Jerand added: “The police think it’s a very wise move and that the municipality made a good decision. “Keeping the lights on creates security and is in line with our common efforts to increase security under current conditions.“

Vigilante groups have formed in Ostersund with some even joining police in nightly patrols. Attacks have included the shocking attempted rape of two 10-year-old girls at a bus stop. Another assault saw three young men wrestle a woman to the ground before trying to rip her clothes off. However, the victim managed to fight back and escape. In a separate attack a man in his 20s punched a woman in the face before running off. Suspicion has been cast on a large migrant camp on the edge of town. However, so far police have been unable to find the perpetrators. In a recent press conference police chief Jerald said the attacks were unusual because none of the culprits appeared to be drunk.

He said: “The cases of the sexual harassment and attempted rapes have involved groups of up to three people. What stands out is also that none of these perpetrators have been under the influence. "Now the police are going out and warning women against travelling alone in the city. We have seen a worrying trend. "This is serious, we care about the protection of women and that is why we are going out and talking about this." Other shocking incidents involving migrant attacks have rocked Sweden.
