Stoned sheep have allegedly gone on a 'psychotic rampage' and are causing havoc after eating cannabis plants which were dumped in a quiet village.

The remains of an illegal cannabis factory were fly-tipped in the quiet village of Rhydypandy in the Swansea valley in South Wales, and worried locals fear the sheep have been munching the herbs after they exhibited some very odd behaviour.

County councillor Ioan Richard said the sheep have been 'roaming the village' causing havoc and claims they have even been breaking into homes and getting killed by cars while in a daze.

Mr Richard said: 'There is a flock of sheep roaming the village causing a nuisance.

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

He says locals are concerned the rest of the flock may discover the remains of the cannabis plantation dumped on the road.

He said: '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.'

The worried councillor has been waging a crusade against frequent fly-tipping in the countryside in his area.

He said the cannabis factory remains spotted by cross roads above Salem Chapel near Rhydypandy was the latest danger.

Mr Richard said that there had already been instance of sheep being killed in the village after straying into the road in the neighbouring village.

He said: '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.'

A spokesman for Swansea Council said it acted swiftly to clear the cannabis remains today - but could not confirm if sheep had eaten it.

He added: 'We made the police aware of this incident as soon as it was reported and arranged a site visit together.
