Brittain was charged with assault with a deadly weapon and released later that morning after posting a $30,000 bond.
The sophomore missed all of last season after being suspended for violating an unspecified team rule. He attended Mesa Community College and was readmitted by the school in January and participated in spring practice.
The University and football staff would not comment, although associate Athletic Director Rocky LaRose said that the athletic department was "aware of the situation, and taking it seriously."
Ironically enough, Brittain was praised by his coach at Mesa for being a great influence on and off the field.
"He's a good kid," said Dan Dunn after Brittain returned to Arizona. "I never saw anything to cause concern."
