The Irish Society for Prevention of Cruelty to Animals has launched an investigation after a monkey was discovered trapped without food or water in a van belonging to a travelling show.
The monkey had been locked inside a filthy cage with no light for more than a week.
He was discovered by a mechanic carrying out repairs on the van at a garage in Stradbally, Co Laois.
The ISPCA said the animal was dehydrated and traumatised and has been taken to a monkey sanctuary for veterinary treatment and rehabilitation.
It will remain there indefinitely.
