After Alison's firm was targeted, the officers working on her case told her police were also investigating similar crimes in other parts of the UK.
Alison's haulage firm, which moves millions of pounds around the country each year, subcontracted to a smaller transport company for a job earlier this year. She says she sometimes does this when her lorries are busy or in the wrong place.
"Their insurance was in place, their operators' licence was in place," she says. "It looked great." The lorry arrived at the manufacturing company, a forklift truck loaded it up with DIY products and the lorry drove off, she says.
But unknown to Alison and the manufacturers, the lorry had been using fake number plates. It disappeared with the cargo worth £75,000.
"The first we knew about it was the destination company rang us and said, 'where's our load gone?'" Alison says. She tried to ring the subcontractor, but the number had been disconnected.
