AIBU police report.

[ThisOchreLemur]

I did report an email received from ex partner to the police. Has been a week and I did not receive my statement or an update about the investigation. I did emailed the police officer two times but they did not answer. I know police is very busy with more serious crimes but since receiving this email I do worry about my safety and I do not want to see my ex partner.
What can I do?
Thank you

Here is the email: "Dear ThisOchreLemur,

As a Mother I completely respect you. As an individual, I consider you dangerous.

One day, Karma was WILL catch up with you. One day the metaphorical ’silver bullet’ that you use WILL find you.

This, you will never escape. Good luck.

Regards,
ThisOchreLemur ex partner. "

Those those wrote don’t do, they don’t leave trails.

It’s obviously an angry and unpleasant email but in isolation it’s not threatening. It’s saying that eventually karma will catch up with you, which is a) bollocks and b) doesn’t imply any threat to harm you. However, definitely keep it (and any other messages) because it would still be evidence if things escalated to threats, or if these sorts of messages became such a common occurrence that they constituted harassment.
