Thieves broke into two vans parked near a building site in Marine Parade, Seaford, to steal tools.
A orange Paslo nail gun, worth almost £400, and Oakley sunglasses were stolen when the door of a white Astra van was forced open around lunchtime on Thursday February 20.
That morning a Mercedes Benz Vito van had its front passenger side door damaged in an attempt to gain entry.
Sergeant Stuart Mullins said: “Both vehicles belonged to tradesmen working at a nearby building site and it is thought that both vehicles were targeted specifically for tools.
“If anybody saw anything or knows the whereabouts of the stolen items they are asked to contact police on 101 or firstname.lastname@example.org or the independent charity Crimestoppers on 0800 555 111.”
