SAN JOSE, Calif. -- A 72-year-old San Jose man violently assaulted during a carjacking incident is sharing new video of the aftermath of the attack.
The video shows Hector Estrada falling to his knees on the lawn in front of his home on Coldwater Drive, then slumping onto all fours for a moment before standing up again.
A 14-year-old boy has been arrested for allegedly carjacking and assaulting Estrada in his own driveway Wednesday morning.
The attack was captured on the retired plumber's surveillance camera.

Estrada says the confrontation began when the suspect approached him while he was unloading groceries in his driveway.
Estrada says the suspect pulled a gun and demanded his keys.
"I said no way. I'm not going to give them. And then he showed me his gun and stuff like that, and I said I don't care if you have a gun. I'm not going to give you my keys. He reached and grabbed them," Estrada told ABC7 News Thursday.
The carjacker then hopped into the car and tried to take off, but Estrada wasn't about to give up without a fight.
That's where the surveillance video of the actual attack he shared with ABC7 News on Thursday begins.
"I reached in and grabbed it and tried to pull him back. He punched me and broke my glasses," Estrada explained.
In the video, the attacker can then be seen exiting the vehicle and punching Estrada several times in the head.
"I started bleeding and then I couldn't see anymore so I just went around the car."
At this point the attacker heads back into the car and takes off.
San Jose Police say that 10 minutes after Estrada was carjacked they got another report of a hit and run crash involving Estrada's car.
The suspect reportedly ran a red light at Story Road and McGuinness Drive and hit another car.
The suspect then fled the scene, leaving Estrada's car behind.
Detectives were able to track down the 14-year-old suspect later that evening and booked him into Santa Clara County Juvenile Hall on charges of carjacking, robbery, assault with a deadly weapon, and elder abuse.
Estrada is a father of three, grandfather of six, and a great grandfather.
He told us that he wasn't afraid of the attacker, mainly because he's suffering from a terminal pulmonary illness and doesn't have a long life expectancy and he has little to fear in life anymore.
