Hanescu appears to spit at crowd
Victor Hanescu has apologised after being fined almost £10,000 for his behaviour at Wimbledon on Friday.
TV pictures appeared to show him spitting towards fans after allegedly being verbally abused during his match against Daniel Brand.
In a statement, the Romanian said: "I lost my control briefly in the fifth set after another insult from someone in the crowd.
"I should never have done that but I am human and I made a mistake."
Hanescu said he had been provoked, claiming: "There were people in the crowd that had been insulting me since the beginning of the match.
"I was winning, had four match points in the third set, but unfortunately I could not close it out. Then I got a leg injury at the end of the fourth set.
"I would like to apologise to the fans, the All England Lawn Tennis Club and everyone else for my behaviour."
The controversy unfolded on Court 18 as Hanescu found himself 3-0 down in the fifth set of the third round match with Germany's Brands.
The match finished 6-7 6-7 7-6 6-3 3-0 when Hanescu retired citing a leg injury.
He had earlier squandered four match points and the world number 38's frustration was clear as Brands, ranked 98th in the world, clawed his way back into the match.
Tournament referee Andrew Jarrett announced that Hanescu would be docked £5,000 for unsportsmanlike conduct and the same for not trying hard enough.
The latter related to the Romanian seemingly committing deliberate foot-faults to end the match.
A standard offence of unsportsmanlike conduct carries a maximum fine of $10,000 (£6,600).
Four spectators were arrested under the Public Order Act after Hanescu complained to police officers.
Scotland Yard said on Saturday that the four arrested men, three aged 30 and one aged 29, had been bailed to return on 16 August pending further enquiries by officers.
