Her plea follows reports of the accidental shooting death of a five-year-old boy in Clarendon yesterday.
Up to press time, investigators were trying to determine whether the child shot himself or was shot by his three-year-old cousin.
The weapon belonged to the children's aunt, a police constable assigned to the Clarendon Special Squad. The weapon used was a Glock pistol which, according to police sources, requires at least 10 pounds of force to fire one bullet.
"I am making a call for every Jamaican who owns a firearm to ensure that it is kept out of the reach of children," Clarke told The Gleaner last evening.
