Emma Raducanu was targeted by a man who “exhibited fixated behaviour” during her second-round loss to Karolina Muchova at the Dubai Tennis Championships, the WTA said.

An emotional Raducanu, 22, was seen hiding behind the umpire’s chair two games into the defeat by Muchova.

“On Monday, February 17, Emma Raducanu was approached in a public area by a man who exhibited fixated behaviour,” said the Women’s Tennis Association.

“This same individual was identified in the first few rows during Emma’s match on Tuesday and subsequently ejected.”

The man has been banned from all WTA events, “pending a threat assessment”.

Raducanu alerted the chair umpire to the situation and was comforted by 14th seed Muchova as the individual was removed from court three.

The Briton returned to the court to applause from the crowd and continued playing, but fell to a 7-6 (8-6) 6-4 defeat.

In 2022, a man who walked 23 miles to the London home of Raducanu was given a five-year restraining order.

The WTA said: “Player safety is our top priority, and tournaments are advised on security best practices for international sporting events.

“The WTA is actively working with Emma and her team to ensure her well-being and provide any necessary support.

“We remain committed to collaborating with tournaments and their security teams worldwide to maintain a safe environment for all players.”

The Dubai Tennis Championships said it “fully supported” the WTA’s statement, and subsequent action taken by the governing body of the women’s game.

“The tournament security team worked in collaboration with the WTA security team to proactively identify and immediately eject the individual in question from the stadium,” said tournament organisers.

“We support the WTA’s decision to ban the individual in question from all WTA events, and share the tour’s longstanding commitment to player welfare, safety and wellbeing.

“We thank Emma for her contribution to this year’s tournament and look forward to welcoming her back next year.”
