A former firefighter in Chile has been arrested for starting a terrible fire that killed 137 people and destroyed many homes in February.
He was supposed to help put out fires, but he is accused of setting one on purpose in the Valparaíso region.
Police think he did it to feel like a hero and get involved in emergencies, even though he had been disciplined for rushing to a fire without permission before.
This is the third arrest related to the fire, as investigators believe the three individuals planned to make money from fighting the fire.
