Swiatek gets extra security after Miami Open harassment

"The Miami incident appears to be a direct transition from verbal aggression online to harassment in the real world," representatives of the world No.2 said. "He was aggressive and taunting."

Swiatek's team reported the incident to 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 later 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 incident happened a little over a month after a spectator was removed from the Dubai Championship after causing 2021 US Open champion Emma Raducanu distress by exhibiting "fixated behaviour" towards the British player.
