The fright came after 22.30 that a large group of young people were stolen by four carers in the school.
One of the robbers had a knife and he threatened the young people as long as and the other three carers raised their business.
– Handbags, clothing, belts, jackets and pillars, said Persson Street at the policing center of the South Division.
– One of the objections was hit, but not with a knife.
The police sent a number of visitors to the site.
The robbers are described as people in their 17-18 year olds. Two of them had Canada Goose jackets, two Parajumper banners.
