A mechanic found the concealed GPS under her car while it was at a London garage for a routine check earlier this week.Katie, 33, said: "I felt physically sick when I spoke to my mum and she told me how a mechanic had found a device hidden on the undercarriage of the Range Rover.
"It was found on Tuesday morning as I was working on publicity for my new book. The first thing I thought about was my kids and their safety. I needed to be with them."The garage had my car on a ramp and spotted this tracker.
