Officers are seeking out further evidence of what happened and who did it.
“Police are keen to speak with any person that may have any information concerning the reckless damage,” said Guernsey Police.
“Police also urge anybody that has property both private or commercially in the surrounding areas with CCTV to get in contact so we can check the footage which may further assist with our investigation.”
