(Reuters) -Polish world number two Iga Swiatek has been given extra security after a spectator at the Miami Open verbally abused the five-times major champion during a practice session last weekend, the BBC reported on Wednesday.
The man shouted personal insults about Swiatek's family and had previously sent abusive online messages to her through social media.
"The Miami incident appears to be a direct transition from verbal aggression online to harassment in the real world," Swiatek's representatives said. "He was aggressive and taunting."
The BBC said Swiatek's team reported the incident and that tournament organisers and the WTA put extra security measures in place around the Pole, who is scheduled to face Philippine wildcard Alexandra Eala in the quarter-finals on Wednesday.
"Security is a top priority. We monitor the network to catch these types of issues," Swiatek's spokesperson said.
"Constructive criticism is one thing, and threats, hate speech or even disturbance during training is another - this cannot be condoned."
The WTA told Reuters player safety was a top priority.
"There are comprehensive security protocols in place to make sure that any incidents are handled promptly and effectively," the WTA said.
"The details of these are not something we discuss publicly, but we are steadfast in our commitment to maintaining a safe environment for players and everyone attending one of our events."
The incident involving Swiatek happened a little over a month after a spectator was removed from the Dubai Championship after causing 2021 U.S. Open champion Emma Raducanu distress by exhibiting "fixated behaviour" towards the British player.
