At about 4:20 a.m. Sunday, Ashwaubenon officers responded to a crash in the 2100 block of South Broadway Street where a vehicle struck a light pole.
Officers found Bierhals, who said he was coming home from a graduation party.
Officers processed him for OWI 1st Offense and he was released to another adult who signed a Responsibility Agreement to not allow the subject to operate a motor vehicle for the next 12 hours.
At about 7 a.m., another officer was working a traffic detail for a Triathlon at the entrance to Ashwaubomay Park and recognized Bierhals from the previous arrest operating another vehicle. The officer stopped him and he was again processed for OWI 2nd and taken to the Brown County Jail.
"He drove into where there was a crowd of people, and he was intoxicated and that's a scary situation that's definitely a recipe for a disaster if there has ever been one," said Capt. Jody Crocker with Ashwaubenon Public Safety.
Ashwaubenon Public Safety is talking with the Brown County District Attorney's office to see if they can criminally charge the adult who signed the agreement.
If Bierhals does post bail, the court ordere he cannot consume any alcohol or enter a bar or tavern.
