Organisers of the Isle Of Wight Festival have said that up to one in five tickets in circulation for the event were fake.
A spokesperson for organisers Solo said that the problem prompted extra security checks on Friday (June 8), causing delays.
A woman, Sherrell Davenport, has been charged with fraud following the discovery of hundreds of fake tickets for the final day (June 10) event, which was headlined by The Rolling Stones.
Davenport will appear before magistrates on June 19.
Hampshire Police arrested two other suspects who were released on bail pending further enquires.
One victim of forgery had paid £320 for a ticket, but was refused entry.
Meanwhile, police searches at the site entrance resulted in 169 people being found carrying drugs.
About half were bailed for possession of class A and B drugs, with the remainder cautioned for possessing class C narcotics, reports BBC News.
