What previous incident in 2022 involved the same man who disturbed Emma Raducanu at the Dubai Tennis Championships?

In 2022, the same man who disturbed Emma Raducanu at the Dubai Tennis Championships had walked 23 miles to Raducanu's London home, demonstrating concerning stalking behavior. Following this alarming incident, authorities issued a five-year restraining order against him.
