Detectives from Mitchell Crime Investigation Unit are investigating following a burglary at a self-storage facility in Seymour last week.

The unknown offenders stole a fishing boat and trailer with a registration of Y57928 as well as boxes of distinctive clothing.
Detectives have also released images of the stolen boat and clothing in the hope someone will recognise them.
