I had to let an employee go early last year, she then (in a drunken frenzy) sent myself and her team leader abusive texts of a sexual nature, the silly girl even sent voice messages to my voicemail.
When I reported her to the police (Leicestershire) they could not have been more helpfull. The girl admitted to sending the messages, (she couldnt really deny them) she was charged with the same offence as caz 247's ex and (because of the nature of the texts) she is on the sex offenders register, so go to the police is my advice
