I am thinking if he is stupid enough to call you then he is likely to call other people on it, or even his own house that he can be traced that way - what a moron!
Sorry for the delay in the update!
DH was able to do a trace on the phone and obviously liased with the police and gave the police the whereabouts on the phone yesterday afternoon...he is just waiting to hear from his 'police contact'... so fingers crossed
However what does annoy me is that its only due to my DH's job that this has been done and of course he has pushed it. I dont think it would have been traced otherwise
The man did ring once more that evening when my friend was round she is much more blaze than me and told him what she thought of him!!!!!
Terrible business, bad enough getting your phone nicked never mind the verbal abuse, feel bad for you. Hopefully he will not ring again and he will be caught.
