St Brelade residents have had to fork out hundreds of pounds in repairs after a number of cars were vandalised on Clos des Sables.
Jersey Police say three incidents of malicious damage have been officially reported on the estate in the last few weeks.
Officers are continuing to investigate the spate of incidents where possible, but a Police spokesperson says some lines of enquiry have been exhausted.
The cases remain on file in case any new information comes forward.
