Pittsburgh police are investigating after their emergency radios were hacked by what seems to be a pro-Nazi group. Authorities say EMS transmissions were interrupted yesterday afternoon by someone who played Nazi songs over the frequency, according to KDKA-TV. The report states that the hackers also played a robotic voice that made a death threat toward “the Pittsburgh mayor.” A Pittsburgh Public Safety spokesperson says they are in contact with Allegheny County Emergency Services in order to fix the issue.
