It is not so much a case that the police cannot take action but they won’t.
Unless there is danger to life or limb, they will not get involved.
There is nothing to stop you making a civil application for an injunction to prevent further contact however whether the emails emanate from Switzerland or Scotland.
You will need a physical land address in order to serve documents which would need to be served at the address both in Scotland and Switzerland.
Can I clarify anything for you?
Please rate the service positive.
The thread remains open for further exchanges.
The police simply do not have the resource to deal with international issues unless life is at threat.
If the culprit was in the UK, and you had an address,the situation will be completely different.
You can always contact the police in the country where the culprit is.
By all means make a complaint to the chief constable but I cannot see going anywhere.
I'm not a policeman remember, I'm just telling you what will happen.
The police are not powerless. They just choose not to exercise the power because the cost of doing so would be disproportionate to the problem.
The threat of legal action can provoke a more extreme reaction in which case you would make an emergency application to court and if the injunction was breached further, he would be arrested. The difficulty you have of course is the multi national jurisdictional nature of this.
