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.

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.

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