Bristol arrest after mephedrone worth £1m found in car
A driver has been arrested after more than £1m of the drug mephedrone was seized from a car in Bristol.
A silver BMW was stopped as it left the M5 at Cribbs Causeway on Thursday and 50kg of the illegal drug, also known as "meow meow", found in the car.
The arrested 41-year-old man remains in police custody.
A police spokesman estimated the haul to have a street value of 1m to £1.25m and said it showed there was still demand for the drug in the UK.
Last year, mephedrone was made a Class B substance after the decision was taken by the government to try to reduce its harm.
Previously it had been labelled as plant food or bath salts and sold as a so-called "legal high".
Paul Bunt, from Avon and Somerset Police, said that one of the most dangerous things about the drug was that little was known about its long-term effects.
