Just a little more info we managed to get,  the car type and model still unknown,  they managed to get the number plate but when checked on the police computer the number did not exist. It happened just south of Barcelona, they had just switched to his wife driving as he was very tired, and according to the police, the robbers target women drivers as they are easier to frighten into stopping.
Can you imagine how terrified his children must have been?
They will live with this memory for a long time.
There is a lot more crime round here than we ever thought is'nt there?
