A case of road rage led to a wild scene at Blackstone and McKinley in Fresno.
A 51-year-old man stopped to help when a pickup broke down.
A second truck driven by a 64-year-old man pulled up behind and police say the 51-year-old thought the truck was too close, got angry and head butted the driver of the second truck.
A Good Samaritan tried to stop the attack but police say the 51-year-old stabbed him.
The suspect took off and a block away another man tried to stop him but he was stabbed too.
The suspect was arrested and is charged with two counts of assault with a deadly weapon.
The two stabbing victims are in stable condition.
