Four people have been arrested after police seized 19 canisters of laughing gas from a vehicle in the Appleby area.
Officers stopped the Audi RS6, from the Leeds area, on Friday June 5 at around 11pm.
As well as the canisters of nitrous oxide, also found in the vehicle were a significant number of balloons, and over £1,500 in cash.
All four occupants of the vehicle were arrested on suspicion of possession with intent to supply a class C drug.
They remained in police custody overnight.
Detective Superintendent Dan St Quintin, Gold police commander for Appleby Horse Fair, said: “This was another successful proactive intervention by police aimed at keeping people at the fair safe and preventing criminality.
“Nitrous oxide poses serious and well-documented risks to health and is illegal to possess or sell for recreational use.
“Our officers will continue to act against anyone suspected of being involved in criminality – regardless of which community those involved belong to.”
