The Women's Tennis Association says 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.

British tennis star Emma Raducanu was visibly upset as tournament officials in Dubai ejected a spectator showing "fixated behavior" toward her during Tuesday's second-round match against Karolina Muchova.

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.
