PC Simon Beaney is appealing for witnesses after caravan parks in Seaholme Lane, Mablethorpe, were targeted by thieves.
Throughout January, entry was forced into a large number of storage sheds adjacent to the caravans and the contents strewn around the site.
Until all the owners have been able to attend and check, it is not known precisely what items have been stolen.
PC Beaney said: “We work closely with park managers and caravan owners to improve security during the vulnerable winter months but encourage all residents living near to caravan sites to help us by being vigilant and reporting any suspicious activity they see.”
Anyone with information should contact PC Beaney at Mablethorpe Police Station by dialling 101 and quoting incident number 89 of January 31. Or you can report crimes anonymously by contacting Crimestoppers on 0800 555 111.
