Glastonbury Festival is on course for its lowest ever crime rate.
Just 12 arrests have been made since the start of the festival on Wednesday, down from 31 at this point in 2015.
Last year's event had the lowest crime rate in the festival's 46-year history, but 2016 could set a new record low if this trend continues.
A spokesman for Avon and Somerset Police said that approximately 90 crimes had been reported, down from 210 at this time last year.
The majority of arrests were for drug use, while most of the crimes reported were for theft.
The crime rate has been low this year despite the ban on legal highs coming into effect in May, making a range of psychoactive substances illegal.
Paul Bunt, head of drugs strategy at Avon and Somerset Police, said: "Psychoactive substances are not a big problem at Glastonbury. We've been aware of psychoactive substances for six years and we work closely with Glastonbury festival organisers around this."
Last year, Glastonbury Festival's crime rate was the lowest ever, with just 75 arrests and 246 reported crimes overall.
The police force have been presenting a friendly face to the public and asking campers to pose for selfies with them as part of a competition.
Many campers have posed for photos in fancy dress, and some officers have even let people wear their helmets for the photographs.
Festival-goers have also been able to receive updates from the police via messaging service WhatsApp, which the force has used to keep people updated as they travelled to the festival on Wednesday and Thursday.
