Stoned sheep have apparently gone on a rampage after eating marijuana plants which were dumped on the side of a country road.

It's believed the drugs were offloaded after a drug bust in the Welsh town of Rhydypandy and locals fear the sheep have been munching on the plants.

County Councillor Ioan Richard raised the alarm.

"There is already a flock of sheep roaming the village causing a nuisance," 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."

He warned of the dangers of the rest of the flock discovering the remains of the cannabis.

"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 added that there had been a number of sheep killed in the village after wandering dazed and confused onto the 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."
