Honolulu Police are investigating a violent road rage incident that was caught on camera.

38-year old Christopher Louie said the attack happened around 9:30 Friday night, while his girlfriend and two kids were also in the car.  His family was driving home on Kapiolani Boulevard from the store, when he was abruptly cut off by a moped.

"At that point I honked at him, just because it was a dangerous thing to do. I wanted him to be aware that we were right behind him.” Said Louie, “He got mad at that, he threw his arm up."

Both drivers made a left on to Cooke Street, where Louie said the driver stopped in the middle of the street, blocking traffic.

"He gets off of his moped, and he approaches the car, I roll my window down." Said Louie.

Louie said his girlfriend recorded the incident on her phone, which received a wide outcry after it was posted on social media.

"He just starts hitting me with his fists and with a chain wrapped around it.” Explained Louie, “He hit me about two, three, maybe four times.”

Louie said he tried to defend himself before the man got back on his moped and sped off.

Louie says they called police and tried to catch his license plate but there wasn't one.

"I was just shocked more than anything because we live in a really safe neighborhood, you know it's Kaka’ako, very family friendly and you don't expect to see that sort of thing happen here." Said Louie.

Louie suffered injuries to his lip and shoulder, and said although he’s glad his family is safe, he’s seeking justice for what happened.

Honolulu Police say this case is classified as a first-degree unauthorized entry into a motor vehicle.  It's a class C felony punishable by up to five years in prison. 

Anyone with any information is asked to call police.
