Police now say six people were arrested over drug offences at the Lockdown festival in Powderham over the weekend. .
Two men had sneaked backstage - they were caught and their vehicle was searched, which led to further searches at a hotel in Exeter and suspected drugs being seized.
They are still in police custody - along with a third man who officers say tried to sell drugs to a security guard even though he was wearing a high-visibility jacket at the time.
Three other men, two from London and one from Exmouth, have been questioned on suspicion of intending to supply drugs - they have been released pending further investigations.
There were two arrests for assault, one for carrying an imitation firearm and one linked to a domestic assault at the festival - police also seized thousands of canisters of nitrous oxide.
