Ioan Richard has cautioned locals about the possibility of an “outbreak of psychotic sheep rampaging through the village” after suspected cannabis plants were discarded in the countryside near Rhydypandy.

Police officials believe that unwanted plants from a local cannabis factory were dumped at a popular fly-tipping site in the area.

Only Mr Richard has connected the incident to an already troublesome flock of sheep.

He told the South Wales Evening Post that the animals had already been “causing a nuisance” for locals and he “dread to think what will happen if they eat what could well be cannabis plants”.

Swansea Council said police are aware of the incident.
