NEWTON, Mass. (WHDH) -- A Newton man was held on bail after allegedly pulling a gun on another driver in an apparent case of road rage.

Byung Gin Kang, 21, of Newton pleaded not guilty on Friday after allegedly pulling a gun on a 34-year-old man. Police said the victim may have had trouble looking around a large snow bank and may have cut off the suspect. The two ended up pulling over and that’s when Kang allegedly pulled the gun.

“The defendant was confrontational. Both parties exited their vehicles and the defendant allegedly stated ‘Do you want to go?’ while pointing a handgun at him,” said prosecutor Alexandra Watson.

What Kang didn’t realize was the victim has a second degree black belt in Brazilian Jiu-Jitsu and tackled the suspect near the corner of Dedham Street and Wendell Road in Newton, grabbing the gun until police caught up with Kang and arrested him.

Prosecutors said the gun was an unlicensed sawed-off .32 caliber revolver loaded with five rounds.

Kang’s lawyer said prosecutors have the story wrong, saying Kang acted in self defense.

No one was injured. Officials did offer advice for people in a similar situation.

“Any time somebody is faced with a gun being pointed at them, a knife being pointed at them. Don’t try to be a hero. Don’t try to do anything stupid. If you feel you’re about to be murdered, if you feel you’re about to be stabbed…obviously you might what to try and do something to try to protect yourself. Anytime you’re involved in a situation and there is a gun, don’t do anything stupid. Don’t try to be a hero,” said Lt. Bruce Apotheker of the Newton police department.

The suspect was held on $10,000 bail. If he posts bail he is ordered to stay away from the victim.
