Ten people have been arrested following a police crackdown on party drug mephedrone, commonly known as Mcat or meow meow.

Dyfed-Powys Police executed 12 warrants in Pembroke, Pembroke Dock, Haverfordwest and Milford Haven yesterday (Thursday), resulting in the arrests.

All have been bailed pending further enquiries.

These operations also enable police to gather key intelligence, which can be significant as the investigations develop a police spokesman said.

Inspector Carl Roach said: “This enforcement action follows a continued and robust campaign of raising awareness of the dangers of this drug, which became illegal in 2010 when it was classified as a Class B drug.

“This has included work within the local schools – and additionally our school liaison team of officers will continue to raise awareness and educate young adults about the dangers of this drug, which is seen as a new drug on the block.”

Inspector Roach also highlighted that Dyfed-Powys Police is planning further enforcement activity over the coming months to ensure that this effective and successful momentum continues.

Anyone with information regarding the use or distribution of this drug should contact police on 101, or via Crimestoppers, anonymously, on 0800 555 111.
