A 32-year-old Brea man was stabbed in the stomach Sunday morning, and police later arrested a suspect.
The victim, James McGrath, 32, of Brea was in the 200 block of South Flower Street in Brea when he was stabbed, officers said. Police said he and another man were arguing about an earlier "traffic altercation in the area of the Orange and Riverside freeways."
After getting a description of the man who stabbed McGrath, Brea police issued an alert.
Fullerton police shortly afterward saw a man fitting the description at Harbor and Valencia streets and arrested him, Brea police said.
Thomas Eugene Fay, 47, of Stanton was booked into the County Jail on suspicion of aggravated assault.
McGrath was taken to a nearby hospital and is in stable condition, police said.
