DUBAI, United Arab Emirates (AP) — Concern over a man who’d exhibited “fixated behavior” caused Emma Raducanu to approach the chair umpire in tears and take an unscheduled break in her second-round match at the Dubai Championships, the Women’s Tennis Association said Wednesday.

Raducanu had reportedly encountered the man multiple times and received a letter from him in person on Monday.

Emma Raducanu was approached in a public space "by a man who exhibited fixated behavior" and the same man was spotted in the first few rows during her match, the WTA said.
