COVINGTON — A man is accused of chasing three children from a Covington park and then stabbing a 9-year-old boy who fell behind. The Courier Journal reported Esteban Portugues, 35, was arrested Friday and charged with second-degree assault. The child’s family said the boy was playing basketball with two other children Friday night. Covington police say Portugues, armed with a machete, and two other men armed with knives then entered the park. Police say the children tried to flee, but the “9-year-old was not able to keep up with the older juveniles.” The child was stabbed in the back of his right shoulder, and police described the wound as not life-threatening. Spokesman Brian Valenti said the attack may have started over the children playing basketball, but that hasn’t been substantiated.
