An Arrowtown museum is warning others in the area to take stock of their possessions.
Police are hunting a woman dressed in a large overcoat who strode into the Lakes Districts Museum on Monday afternoon and stole a large silk kimono.
Her actions were caught on CCTV.
Museum director David Clarke says the woman's methodical approach seems suspicious and he wants others in the area to have a look around.
He says the entire town has very good CCTV coverage so if anything is missing they should also check the tapes.
