A gunman who killed 11 people, including himself, at an adult education centre in central Sweden may have been a student at the school, police said on Thursday, as they described chaotic scenes after the country's deadliest mass shooting as being like an "inferno".

Andersson was said to be a recluse who had maintained little contact with his family for years before tragedy unfolded at Risbergska School in Orebro

The facility offers adult courses, including Swedish language classes for immigrants. Law enforcement officials say the shooter, who Swedish media have identified as 35-year-old Rickard Andersson, may have been a student at the center.
