A pre-school in St Brelade is appealing for help to stop its outdoor area from being repeatedly vandalised.
Communicare says its main storage shed has been flooded and a large wooden playhouse damaged - with windows broken, drinks poured and tobacco left inside.
The garden has been broken into weekly since the start of term, including last Wednesday night when a staff member caught a group of teenagers in the shed.
The nursery - which has been caring for children in the parish for more than 40 years - is asking neighbours and passers-by to be vigilant and report anything suspicious to police in the hope of stopping further damage.
