The grenade blasted on Thursday 15th April 2021 morning when the boy climbed onto the rooftop of their house to fix a roofing tile.
As he reached the rooftop, he saw a cord fastened to a metal object which he took down and played with it.
His sister and mother warned him against playing with the object which shortly started exuding smokes.
The executive secretary of Gacurabwenge sector, Christine Nyirandayisabye has told IGIHE that the victim immediately threw the object to a nearby avocado tree and exploded instantly.
The boy was injured on the shoulder and arm, on the belly around the waist. He was immediately taken for medical attention.
Local leaders rushed to the scene where they realized that it was a grenade that had been laid on the roof of their house.
Nyirandayisaba appealed to the residents to alert local leaders in case they find strange objects and avoid playing with them.
“We would like to comfort residents and reassure that their security is guaranteed. We also advise them against playing with strange objects,” she said.
