A system admin is wreaking havoc in San Francisco.

Terry Childs, 43, pleaded not guilty in San Francisco Superior Court, after being arrested on July 13 for computer tampering. He will remain in police custody on $5 million bail, while his next bail hearing is scheduled for July 23.

Child is accused of changing the administrative passwords of San Francisco’s FiberWAN network system, which makes accessing the system impossible now without the passwords only he knows. Furthermore, his motifs for doing it still remain unknown, but suspicions are his actions may have been triggered by a conflict with a superior.
