The break-in at the outbuilding to a property in Station Road happened on Tuesday, April 16.
It is not the first time the outbuilding has been targeted, police added.
A Sussex Police spokesman said nothing was stolen during the break-in, but like last time it seemed to have been used by drug takers as it ‘smelt strongly of weed’, they said.
If anyone has information about the break-in which may help police, please call Sussex Police on 101 or report online at www.sussex.police.uk/ro/report/ocr/af/how-to-report-a-crime.
