A Cleveland police statement says officers responded to a home in the northeast Ohio city around 10:30 a.m. Friday. Police say the child was taken to a hospital where he died from his injury.
The names of the child and the father weren't immediately released.
The police statement says preliminary information indicates that the child got his 54-year-old father's gun and shot himself. Police say they are continuing their investigation.
FOX 61's sister station in Cleveland, FOX 8, reports the boy is the son of a 54-year-old Cleveland Police Officer Jose "Tony" Pedro, who was hired in 1993.
FOX 8 reports that it was the older brother of the little boy, Dominic Pedro, who asked neighbors to call 911 after discovering his brother had been shot.
