A suspect in setting fire to a house in which five people died was arrested in the Arkhangelsk region. He partially pleaded guilty, the investigative committee reported. On October 28, the person involved in the case, out of personal hostility towards a 61-year-old man and his family members, threw a burning cigarette butt into the crack of the closet door located on the step.
