Police said Esteban Rodriguez, 38, of Norwalk, received four gunshot wounds and was taken to an area hospital for treatment. His condition is not known.
The officer had been searching for a man suspected in a domestic violence incident when he spotted the man fleeing in a tractor trailer near the corner of Citrus and Walnut avenues.
The man led the officer on a brief chase back to the 6100 block of Catawba Avenue, the location where the domestic violence incident was reported.
The officer approached the man, trying to keep him from going back into the house. Rodriguez grabbed a large pick ax, raised it above his head and approached the officer, police said.
When the man came within several feet of the officer, the officer fired several rounds.
Police arrested Rodriguez on suspicion of attempted homicide of a police officer and domestic violence.
