A psychiatrist who once worked at Waikato Hospital has been charged with sexually assaulting one of his patients in the United States. The alleged assault took place just months before Paul Fox, a US citizen, started work at the Henry Rongomau Bennett Centre. Fox, who also treated the US mass-murderer Adam Lanza, was charged with three counts of second-degree assault after police say he had “a sexual relationship with an adult patient while he was a practising psychiatrist in Brookfield.” The DHB executive director for mental health Derek Wright said the board was confident it undertook all reasonable background checks.
