Police came under attack as they tried to stop an illegal rave in the countryside attended by up to 100 people.
Six officers sustained injuries after allegedly having missiles thrown at them in Beacon Hill, Highclere, close to where Downton Abbey is filmed on the Hampshire/Berkshire border.
A 23-year-old man and 29-year-old woman were arrested on suspicion of organising the unlicensed event.
The woman, from Oxfordshire, was also held for suspected possession of class B drugs.
Officers from Hampshire and neighbouring Thames Valley Police were alerted to the rave at around midnight and say they attended to foil any disorder and disruption to local residents.
