Novak Djokovic fled Flushing Meadows before returning to apologise for his actions at the US Open.

The Serbian has been booted out of the tournament via default after hitting a linesperson with a tennis ball in anger.

After losing a crucial point to his opponent, Pablo Carrena Busta, the World No. 1 lashed a ball with his racket.

And it struck a lineswoman behind at the edge of the court right into the neck.

She was left floored and needing medical help as Djokovic immediately went over the apologise.

While in talks with the umpire, he claimed that he should be given another chance, saying: "You have a game penalty, set penalty, many options."

But after ten minutes of deliberations, the decision was made to default the top seed from the competition.

And the top seed made a quick getaway, getting in his car and looking to leave.

According to The Times, Djokovic had a change of mind and returned to formally apologise for his actions.

Former British number one Tim Henman argued on behalf of Djokovic on Amazon Prime but ultimately agreed the right decision had been made.

He said: "It happened to me in 1995. We were up two sets in the doubles. I hit a ball-girl in the ear.

"Djokovic was not aiming for the line judge, but you have to be responsible for your actions.

"There is no other result but to be defaulted."

In the end, it has been a fine result for Carrena Busta, who took advantage in the first place after going 6-5 up against Djokovic.

The 20th seed said: “Novak is playing amazing tennis. Probably the hardest task at this moment, but there are always options.

"Maybe he will have a bad day.

“Key for me is to be absolutely focused, especially in the beginning of the match.

“Our last match both sets were close, but he knows how to play the big points. He is more experienced than me.”
