A bunch of drugged-up sheep are causing a nuisance in the Welsh town of Rhydypandy, after apparently munching on offloaded cannabis plants on the side of a country road.

County councillor Ioan Richard raised the alarm.

“There is already a flock of sheep roaming the village causing a nuisance, Mr Richard told the South Wales Evening Post.

“They are getting in people’s gardens and one even entered a bungalow and left a mess in the bedroom.

Mr Richard warned of the dangers if more sheep sought out the the dumped drugs.

“I dread to think what will happen if they eat what could well be cannabis plants – we could have an outbreak out of psychotic sheep rampaging through the village,” he said.

He went on to add a number of sheep have already been killed after the loaded flock walked onto a nearby road.

“I told the council officers to make sure it was reported to the police before removing any evidence of what looks like the dumped remains of a cannabis growing establishment,” Mr Richard said.

A Council spokesman said the matter had been taken care of.
