A man armed with an AR-15 rifle helped stop a knife attack during an argument in Oswego.
It happened on Monday at an apartment building on Harbor Drive.
Police say it all began when someone with a knife attacked another person during an argument.
Neighbor Dave Thomas, who witnessed the attack, went into his home, got his rifle and ordered the suspect to stop.
"I ran back into the home, into my house and grabbed my AR-15. Grabbed the AR-15 over my handgun. It's just a bigger gun. I think a little bit more than an intimidation factor definitely played a part in him actually stopping."
No shots were fired.
The suspect was able to get away briefly, before police captured him.
The stabbing victim was taken to a hospital, and is expected to recover.
Police say Thomas has a valid firearm owner's identification card and a concealed carry permit. Thomas says he is also a firearms instructor.
"The AR-15 is my weapon of choice for home protection," Thomas said. "It's light, it's maneuverable. If you train and know how to use it properly, it's not dangerous. And this is just a perfect example of good guy with an AR-15 stopped a bad guy with a knife. And there were no lives taken, so all in all it was a good day."
