A probable cause affidavit alleges the boy pushed and punched a school security officer.He was not in custody when he appeared in court. Commissioner Carin Schienberg allowed the boy to remain in the care of his parents before his April 1 arraignment hearing, court records state.The second defendant who appeared on allegations tied to the incident at the middle school is a 14-year-old girl. Two separate probable cause affidavits assert there is enough evidence to charge her with fourth-degree assault and failure to disperse, or third-degree assault and criminal mischief. An affidavit says she spat in an officer’s face and used racial slurs.Her arraignment was scheduled for Wednesday. She was ordered jailed because her parent was either unwilling or unable to take her home, court records state.
