A police detective inspector can solve it for you in very short order, causing the perp to freeze with terror and delete all or visit jail. You need to take computer and emails or whatever with you to cyberCRIMES division when you visit unless you have expert who can copy all needed to USB stick. Taking computer is best I'd think, and UK police are top-notch on this, maybe best in world (I know that is true for London Metropolitan and Scotland Yard).

Call your police ASAP during early business hours and GET ON with it -- no delay!

Tell them your age so they will work fast. You are lucky to be in UK, they work far more slowly in most of USA, excepting a few states.
