Hi, I am a mobile massage therapist. One of my clients claimed that I stole his $600 which was left on his bedside table. I went to his place on Aug 20th around 8 am, and he rang me on the 21st around 8 am telling me to return his money or he would ring the police. The fact is, that I didn't take his money. He even paid for the massage by a bank transfer; he said he didn't have cash. 2 weeks later, 2 police officers came to my house to interview me. My question is - would I be able to sue him for defamation? After the interview with the police, what would be their next step? Thank you.
