A man, in a fit of anger, went over to his brother’s house in the community of Emerald Hills and shot him Thursday afternoon, San Diego police said.

The 69-year-old man showed up at the home on Selma Place near Roswell Street about 4:10 p.m. He is then suspected of using a rifle to shoot his 61-year-old brother in the shin, San Diego police Officer Robert Heims said.

The suspected shooter was arrested without incident. The rifle was recovered and the victim was taken to a hospital with injuries that weren’t life-threatening.

Investigators are working to determine what led to the shooting.
