There was high drama during the Fed Cup tie between Great Britain and Romania on Saturday as a tirade by Romania captain Ilie Nastase brought Johanna Konta to tears.
Nastase was sent off during Konta's match against Sorana Cirstea after swearing at the umpire and abusing Konta and her captain Anne Keothavong.
Konta subsequently lost her serve in the next game and broke down and started to cry.
The International Tennis Federation said it was looking into "this matter as well as previous comments made by Mr Nastase during the week" - a reference to remarks Nastase made about Serena Williams' unborn child.
During a press conference on Friday, he turned to one of his other team members and said in Romanian: "Let's see what colour it has. Chocolate with milk?"
Clearly upset by what had transpired the day before, Nastase appeared to be in a foul mood on Saturday, and he reacted angrily when Konta and Keothavong had complained of calling out from the crowd during the match against Cirstea.
Nastase called both Konta and Keothavong "a bitch" multiple times as he discussed the matter with officials, and he also swore directly at them.
He was sent off the court by referee Andreas Egli and, after taking a seat in the stands, was then escorted back to the locker room.
When play resumed Konta was able to gather herself and complete a 6-2, 6-3 victory over Cirstea to level the tie at 1-1.
"It was not something anyone should experience," Konta told BBC Sport.
"It did upset me quite a lot and that was shown. I am not one to cry on court. It was slightly embarrassing but it affected me more than I would have liked.
"I know that Fed Cups can be quite emotional and can sometimes take an unexpected turn but it wasn't something I was prepared for.
"Obviously, it left me slightly unnerved but the best I could do was to make it as much about the tennis as possible. I felt I did that and am looking forward to that again tomorrow."
After the match, Cirstea said Konta had overreacted.
"Someone crying cannot stop a match," she said.
"From a tennis point of view, Johanna deserved the win - she is a better player than me - but the behaviour of the British team was exaggerated.
"Why did we stop? Only because Johanna cried? I have never cried on the court because someone told me something. You have to toughen up.
"OK, at 2-1 you take our captain out, that was the right decision, but then at 3-1 I break you and now you cry. I am not saying it was fake, but it was not logical.
"Next time I'm in trouble I will cry, maybe I can go off the court. As Romanians we get double insulted because of our nation but it's OK, we are tough. Tougher than British people apparently."
Before play had even started on Saturday, Nastase took issue with British reporters who had described his comments about Williams' unborn child from the day before as racist.
"He repeatedly called me stupid, asked me why what he said was racist," said Press Association Sport tennis correspondent Eleanor Crooks.
"I explained we simply reported what he said and that it was unnecessary to make such a comment about colour. He said the English were out to get him and called me stupid a few more times."
