(CNN) -- A Warren Township, Ohio, man faces charges of felonious assault after authorities say he fired his rifle at two teens who were attempting to deface his McCain presidential campaign yard sign. Police say the man's sign is the only McCain sign on a street full of Obama signs.
Kenneth Rowles, 50, pleaded not guilty to the charge Monday, according to CNN affiliate WBNS. Bail was set at $10,000.
Rowles told police he was sitting on his porch Saturday when a tan SUV pulled up and a black youth jumped out and ran toward his house, screaming, "This is for Obama."He said another male was hanging out of the passenger window screaming the same thing.
Rowles said he went inside, got his rifle and fired three shots to scare the youths away, according to a Warren Township police report.
He told officers he believes that the men "were the same two that have been destroying his McCain sign."
Just hours before the shooting, Rowles called police and said that a car had stopped in front of his house and that a black male "ran up and said something about Obama," according to the report, and "damaged his sign again."
One of the youths, 17-year-old Kyree Flowers, was shot in the arm, according to a police report. He and the second youth, Patrick Wise Jr., 16, told police they were in the car attempting to leave when Rowles fired at them.
"Kyree stated that he witnessed the homeowner trying to shoot Patrick but he was having trouble chambering a round," the police report said.
The teens admitted that they had defaced the McCain sign several times, Warren Township police Lt. Don Bishop told CNN.
Rowles' is the only McCain sign on a street full of Obama signs, he said.
Bishop said the teenagers probably will not be charged -- and are unlikely to damage campaign signs again, as the incident scared them.
