Police say Jason Sylvain knocked down the Knightscope droid while it was patrolling the parking lot last week. The man faces prowling and public intoxication charges, but it appears the robot gets some credit for arresting its attacker. Stacy Dean Stephens, Knightscope's VP of marketing told CNET that: "The robot did exactly as it was suppose to do. The 'assault' was detected and immediately reported. The alarms on the robot sounded, the suspect attempted to flee the scene and was detained by one of my colleagues and me until the Mountain View Police arrived."

Sylvain apparently wanted to test the security of Knightscope's patrol drones. We're more intrigued as to how he toppled 300 pounds of robot. That might prove useful in the future.
