The officer was reportedly trying to break up a fight when he was knocked off his motorcycle.
Witnesses say the officer was on his motorcycle when he noticed two people fighting.
It's not clear what started the fight or if then men knew each other.
The officer headed down the street to break the fight up, but when he got up close, one of the men turned his attention to the cop.
"when he got there, he honked his horn, and the gentleman that they took into custody turned around and swung at him...and knocked him off his bike, and continued going at him with his fist," said Pam White, a witness.
Witnesses say two people ran across the street to help the officer out, and together, they were able to get the suspect to the ground.
The suspect was arrested.
The officer wasn't seriously hurt, but his bike did appear to be pretty banged up.
