A Schuylkill County judge has revoked the probation of a Pine Grove man accused of calling the Schuylkill County courthouse on Oct. 2 and Oct. 3 and threatening to shoot school children unless the building was closed.

President Judge William Baldwin on Monday revoked the probation of Todd A. Dohner, 48, in two earlier cases. But the revocations don't mean much of a change to Dohner, who remains in county prison under $500,000 straight cash bail on the threat charges.The two cases for which Baldwin revoked Dohner's probation involve harassment on Feb. 16, 2012, and indecent exposure on July 6, 2012. He pleaded guilty in those cases on March 20, 2013. Baldwin sentenced him to 24 months of probation in the indecent exposure case, and 12 months in the harassment case.The indecent exposure happened in a borough park. The harassment charge stemmed from Dohner leaving messages on a Pine Grove woman's voice mail.The threat charges in October violated the terms of those sentences, leading to the revocation.Dohner has a string of offenses in Schuylkill County, stretching back to 1989.In October 2013, he pleaded guilty to making terroristic threats against school officials if they didn't change the color of school buses from yellow to red. In that case, he was sentenced to 23 months in prison but was released on parole.Pottsville police charged Dohner with two counts of felony terroristic threats, two counts of felony criminal use of a communication facility and two counts of persistent disorderly conduct.The calls were placed on the courthouse voice mail late at night on Oct. 2 and in the early morning hours of Oct. 3.The caller said he was the leader of a "terrorist group" and would have his group shoot students at a school from 100 yards away at 3 p.m. if his demand was not met. The courthouse was closed at about 11 a.m. Police traced the calls to Dohner's cell phone.
