What is the proper penalty and admin?

[Nevadaref]

During the 3rd quarter a spectator is harassing a team member on the bench.
The team member leaves the bench area and goes up into the stands to confront the spectator.
The game officials notice the disturbance and stop the game.
What are the proper penalties and to whom? How is the game restarted.

Please cite the current rules book and refer to the new play rulings.
