If you go back to thread 14 around the time this email was sent, Elph had rang the police a week earlier to report mama kaz, eq and cla. It was also at the same time he was being accused of scamming 15k off that woman. We were even discussing the relevance of a c&d so I don't doubt he initiated this.
On the day of the email, he was spotted in Leeds with a new character. I reckon the police had told him what a c&d is and he's found some student in Leeds to write it up. It makes me wonder why Kaz didn't realise at the time it was fake and exposed it there and then as their beef was in full swing. It would also be interesting to know what email address they sent it from. Did she ring the number on the email back in July or more recently?
