A resident of Lysev discovered that there were cockroaches in his apartment. He did not intend to settle with the barren neighborhood, and decided to arrange for them hell (in terms of air temperature).
He pulled a heat gun home, turned it on full power and closed the door tightly. When he realized that the sharp smell of heat was produced by not-heated cockroaches, it was too late. The insects were embraced by the flames along with his things and furniture.
To extinguish the experiment with thermal disinfection traveled up to 5 fire crews and 13 personnel. From the foolishness of the culprit of the incident, they were also slightly burned.
