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 was clearly upset as she approached the umpire during the second game in the match, which she lost to Karolina Muchova.

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.
