The young man had suffered “some sort of mental breakdown,'' San Diego Police Department Sgt. David Jennings said, and was chasing neighbors with a knife and a hammer.
One neighbor armed himself with a handgun and shot the suspect, who was hospitalized with non-life-threatening injuries, Jennings said.
The incident occurred around 7 p.m. in the 10300 block of Moselle Street, Jennings said.
“He was running around with a hammer beating on cars and arguing with neighbors,'' police Officer Robert Heims said.
Heims said the neighbor who shot the man was not taken into custody.
Neighbors said the suspect's parents live on the street where the rampage took place.
