Police swooped on an illegal rave in woods near Devizes on Saturday night.
The woods on the outskirts of Erlestoke have proved popular with partygoers in recent years and both Wiltshire police and officers from the MOD responded to calls about illegal music.
A spokesman for Devizes Police said: "Following the report of an illegal music event overnight near Erlestoke, Officers from Team 2 and MOD Police completed a joint operation dealing with any offences as suspects left the site.
"One male was arrested following a search when drugs were located, a driver was arrested following a positive drug wipe test. Drivers were breath tested leaving the site."
But the police did not prevent the rave from continuing.
