A succession of people appeared at Perth Sheriff Court on Monday in relation to alleged offences committed at T in the Park.
More than 20 festival-goers were charged with a variety of crimes ranging from sexual assault to drugs offences.
The alleged transgressions all took place between Saturday and Monday.
Among the most serious breaches is alleged to have been committed by Alexander Wynn, of Lunderston Drive in Glasgow.
The 55-year-old is accused of sexually assaulting a woman in the Red Campsite on Saturday.
He is further accused of assaulting the same woman by punching her on her body and pushing her, causing her to fall to the ground.
On the same day he is alleged to have assaulted a man by attempting to punch him.
Wynn denies all the charges against him.
* A teenager admitted punching a police officer on Monday morning in an area where buses were waiting to take revellers home.
The officer was on cycle patrol in the bus waiting area when he stopped to speak to a member of the public.
He heard shouting behind him and turned to see what the disturbance was, when Peter Reilly, 18, of Milnacre, Edinburgh, hit him in the face.
Depute fiscal Jim Eodanable told the court the officer’s nose had been hurt but he did not require further treatment.
Sheriff Michael Fletcher deferred sentence until July 21 for reports.
