Rwanda National Police has disclosed that four more patients who were injured by a grenade explosive in Ndera sector, Gasabo District were discharged from Kanombe Military Hospital on Saturday, May 9.

The latest recoveries were the ones remaining on treatment after other seven patients of the same incident were also discharged Friday, May 8.  

The incident took place on Thursday, May 07 after a 25 year-old man identified as Jean Paul Tunezerwe detonated a grenade in a hair salon.

He was a resident of Ndera Sector and a regular customer at this salon. 

Tunezerwe was the only person who succumbed to this incident, which preliminary findings have ruled out terrorism as the motive. 

Detailed investigations are ongoing to ascertain the source of the grenade. 

"We request anyone who met Jean Paul Tunezerwe yesterday to come out and share with us any information you may have about him. Call 112 or 0788311155 (also on WhatsApp),” reads a tweet from police.

In a statement earlier, police said that Tunezerwe entered the salon and proceeded to occupy the seat from where he was to get a haircut, but then told his barber that he had something in his pocket which he tried to show the barber identified as Pacific Niyikiza.

"Inside his pocket was a smoke-emitting grenade. On seeing the grenade, Niyikiza immediately told Tunezerwe to get out of the salon and in the process the grenade detonated,” the statement said.
