An electrician had £10,000 worth of tools stolen by two "relaxed" thieves who broke into his van while he lay in bed.
Martin, 54, who runs Elite Electrics and has traded for 33 years, said: "They were just so relaxed about it. They weren't rushing around, it was obviously just another job for them.
"There was no nervousness or concern. It's very frustrating, what I would do to them if I could catch them."
The pair turned up outside Martin's in Boleyn Way in a black Audi A3 shortly after 5.15am on Wednesday, July 27, and had raided his Transit van and left again within half an hour as Martin prepared to get up for .
Despite alerting Essex Police and supplying them with the CCTV footage of the break-in the married father says he has little from the force.
"There must be CCTV around Chelmsford and down the A12 for them to track the car but the longer it goes, the less likely I am to get them back.
"It is not exactly a petty crime, with the amount of money we are talking about. They haven't just stolen one tool worth £100, it was a good day's work for them."
"They just pulled in and seemed to target my van," he added.
"They didn't even look at anything else or anyone else's vehicles, they went straight for mine, picked the lock and took everything.
"I want them caught, and I want the police to do everything they can.
"What is annoying is that I was probably awake when it happened, lying in bed thinking 'I've got to get up for in a minute'.
