A spurned doctor who sent 9,000 abusive texts and emails to her former Tinder date, his new girlfriend and their colleagues has been jailed in what one magistrate described as the most extraordinary incident in his 34 years on the bench.

Denise Lee, 41, a radiologist, appeared in court in Sydney yesterday, coughing with her face hidden behind a surgical mask as Michael Barko, the magistrate, read out the details of her two brief sexual encounters with Matthew Holberton, a financier. After the relationship ended she sent him 20 texts in one day because she was “really angry”, followed by another 69 texts in under two hours, which ranged from “I want us to try properly” to “I am going to f*** your life up”.
