Arnold was additionally charged for resisting arrest.
Arnold was sentenced to 43 days to two years less one day in the Venango County jail on the riot charge. He was also sentenced to two years probation following his jail sentence for the assault charge, and another year of probation for resisting arrest.
He was given credit for 43 days he has already served in jail.
Bauer was sentenced to 48 days to two years less one day in the Venango County jail on the riot charge. He was also sentenced to two years probation following his jail sentence for the assault charge.
Both were also ordered to pay fines and court costs.
A third defendant in the case, Jamie L. McCool Jr., 20, of Franklin, negotiated a guilty plea in January on a felony drug charge and a misdemeanor disorderly conduct charge.
McCool is scheduled to be sentenced April 8, but in the meantime he was charged last week with robbing and beating up another man in an attempted drug deal March 18 in Franklin. A preliminary hearing in that case is tentatively scheduled today in Venango County Central Court.
Arnold, Bauer and McCool were arrested separately last July for incidents that occurred June 25 and 26. They all waived their preliminary hearings in August.
In a criminal complaint, Franklin police said a man was beaten unconscious June 26 after trying to get $40 back from those who had sold him what he claimed was counterfeit cocaine the night before. Once on the ground, the man was then struck across his face and neck by a thrown bicycle.
Police said McCool set up the drug deal. The sale of the apparent counterfeit cocaine occurred between 9 and 11 p.m. June 25 at the intersection of 13th and Railroad streets.
The attack on the buyer took place about 9 p.m. the following night in the municipal parking lot in the 1200 block of Buffalo Street, the complaint said.
The man told police he was walking in the 1200 block of Liberty when he realized he was being followed by a group of 7-10 people, including McCool, Bauer and Kelletti. As the man walked to the 1200 block of Buffalo, McCool started calling him names and the other defendants harassed and threatened him with violence and used racial slurs, the complaint said.
The man was speaking to a friend on his cellphone and told his friend to call police. As the man ended the phone call, Bauer struck him in the face and jaw area and knocked him to the ground, police said.
Bauer then kicked the man in the head and face. As he was lying motionless on the ground, Kelletti picked up a bicycle and threw it at him, striking him in the neck and head, according to the complaint.
The man suffered a broken tooth, several areas of swelling and cuts, abrasions and bruises, police said.
