A 61-year-old Pleasanton man was arrested following a road-rage incident that included him stabbing a cane-sword into the driver's side door of the victim, according to Pleasanton Police.
Samuel Cangiamilla was arrested on suspicion of assault with a deadly weapon at his Pleasanton home last Friday.
The ordeal started earlier that day on eastbound Interstate 580. Cangiamilla was driving a Jeep and the victim was in a Volkswagon Jetta.
The driver in the Jetta sped ahead of Cangiamilla and then entered the same lane as the Jeep. Cangiamilla then sped ahead of Jetta and merged into the same lane. The Jetta driver then started changing lanes three or four times, but Cangiamilla changed lanes as well, blocking the Jetta.
Cangiamilla exited the Santa Rita Road exit and was followed by the Jetta driver. The Jetta followed for about 2.5 miles to Main Street and Stanley Boulevard. At the red light, the Jetta driver exited his vehicle to confront Cangiamilla.
He then exited his vehicle, and pulled out a cane-sword. The Jetta driver retreated to his vehicle. Cangiamilla held his sword above his waist and started yelling at the other driver, according to police. He then went to the driver's side door and stabbed his sword into the door. The blade did not enter the interior of the Jetta.
Cangiamilla returned to his vehicle and drove into the parking lot on the 900 block of Main Street. The Jetta driver followed to try and get Cangiamilla's license plate number.
In the parking lot, Cangiamilla parked and attempted to open the driver's side door of the Jetta as it passed by. Then he kicked the back the of Jetta.
The Jetta driver called 9-1-1 and left the parking lot.
Officers went to Cangiamilla's residence on the 400 block of Del Sol Avenue and arrested Cangiamilla without incident.
After searching the home, they found a cane-sword similar to the one described by the Jetta driver.
