The incident happened on Saturday evening
A Derbyshire business owner said he has felt "sick" ever since having £7,000 worth of tools stolen from his van.
Mark Anderson has spoken out after a brazen thief stole brand new equipment and personal items from a company vehicle last weekend.
The vehicle, belonging to S A Concrete & Cutting Services Ltd, in Langley Mill, was targeted on Saturday evening (March 30) at around 7.30pm.
Mr Anderson, 48, said the discovery was made when an employee went to pick up his van the following day.
He said the back of one of the vehicles looked like it had been "peeled open like a tin can" with a hammer and crowbar.
Equipment stolen included a Hilti DD250 core drill rig, a Hilti TE80 drill/breaker, a Weka DK13 hand held diamond drill and various small hand tools.
Mark has been left gutted by the incident
Mr Anderson, who is one of the directors of the firm, revealed he had marked the tools as stolen so that if anyone did take them, they'd find it hard to sell them on.
He claims the thief covered up nearby CCTV cameras with a plank of wood.
He is also offering a reward for anyone who thinks they have any information about the tools.
He said: "I felt gutted and sick, I still do to be fair.
"Everyone is demoralised.
"It looks like he has ripped the back of the van open. We found a hammer at the back at the bottom so we're assuming he's smashed into it with a hammer and peeled it open like a tin can.
"All those things cost money but he isn't going to sell it anywhere else."
Mark said the company has had to hire another van temporarily and revert back to using old equipment.
