A witness of a bow and arrow attack that killed five people in the town of Kongsberg recalled on Thursday seeing one of the victims walking on a street with an arrow in his back. Investigators named the suspect as Espen Andersen Braathen, a 37-year-old living in the municipality where the attacks took place. Police had been concerned about signs of radicalisation in the suspect before the attacks, carried out with a bow and arrow and other weapons, a senior officer said.
