A man accused of ramming his dump truck through the security gate at the FBI building in Pittsburgh won't appear in state court until later this month.

Tuesday's preliminary hearing for 48-year-old Thomas Richard Ross, of New Waterford, Ohio, was postponed until Aug. 17.

He also faces federal charges in the July 26 incident, but a court date hasn't been set.

Pittsburgh police cited Ross for allegedly running eight red lights and driving recklessly before being stopped by police near the FBI building. Ross allegedly claimed to have a bomb before speeding off and through the gate. No bomb was found and nobody else was hurt.

Ross doesn't have an attorney listed in court documents. He's charged with aggravated assault, defiant trespass and other crimes.
