BURGLARS raided a self-storage business near Colsterworth on Saturday night, stealing items from around 40 shipping containers.
The thieves made a hole in a fence at the U Hold the Key storage yard on the A1 northbound and used bolt cutters to snap padlocks.
Inside the containers, they made meticulous searches for valuables like jewellery and electrical items.
Martin Strange was among the people who had valuables taken.
He said: “It’s the equivalent of breaking into 40 houses. I can’t think what’s gone. They went for things that were small and expensive.
“I’m sure I’ve lost a few grand, butit will be little things that I haven’t even thought of.”
A police investigation into the thefts is ongoing.
