Dyfed-Powys Police are issuing a warning after plant food has been sold as a street drug to young people.

The food is being sold under the street names of Meow Meow or M cat and is believed to be popular among young people in and around Tenby.

"This so-called drug is basically just plant food," said Chief Inspector Alan Millichip.

"We cannot emphasis enough how dangerous this could be to people who take it."
