Detective Inspector Norman Stevenson said: “We continue to appeal to anyone with information about this incident to get in touch as soon as possible as our inquiries continue.

“Anyone with information is asked to contact Police on 101 quoting ref. no. CF0003930119 or alternatively you can contact Crimestoppers on 0800 555111.
“In particular did you see any vehicles leaving the Harbour area around the time in question on Sunday morning? Or did you see any suspicious activity in the Old Cove area?”
DI Stevenson added: “We also continue to carry out enquiries into a fire-raising and vandalisms at the site of the Aberdeen Harbour expansion.
“I appreciate the similarities of both incidents and the close proximity, however we need to keep an open mind as to whether they are linked.
Final straw at Cove harbour after a 3 year court battle to save the fishing boats. The remaining 5 boats Net store and fishing gear destroyed in huge fire .
“In the meantime additional patrols are being dedicated to both areas to help prevent any similar incidents from occurring.”
Scottish Conservative shadow justice secretary Liam Kerr commented on the matter: “This has plainly had a major effect on local fishermen and the community around Cove Harbour.
