A man is taken away by police, who told members of the media as he was loaded into a police car, that he had been carrying a knife, shortly after Norway's Prime Minister Jens Stoltenberg arrived at a hotel in Sundvolden, Norway, to meet survivors from the shooting at an island youth retreat, Saturday, July 23, 2011. Norway's prime minister and royal family visited grieving relatives of the scores of youth gunned down in a horrific killing spree on an idyllic island retreat. A man who said he was carrying a knife was detained by police officers outside the hotel, as the shell-shocked Nordic nation was gripped by reports that Norwegian gunman may not have acted alone.
