I don't believe they investigated it, they went to the police and they said no thanks. Given policing levels it's probably the standard response ( they should have said the presenter misgendered their son, would have been all over it then
)
Yeah, it's not the parents who look bad when news broke that the beeb sent one email and then called a non responsive number (non responsive number would be generally a dead line)
Nothing to suggest they were paid is there? Hell they are still anonymous, if they wanted to 'cash in' they would have gone public and hope other news outlets would give them some sweet sweet appearance money
Leave me alone or I'll go to the police seems the right thing to do in an instance of harassment does it not?
