A large Ukrainian flag draped around a fan during the Western & Southern Open in Cincinnati on Sunday caused a complaint, and the woman was asked to remove it from the event, officials said.
The issue began during a qualifying match between Russian players Anna Kalinskaya and Anastasia Potapova, which led to one of the players complaining to WTA chair umpire Morgane Lara about the fan in the stands, according to multiple reports.
The fan was told by Lara she was "not being nice" and needed to put the flag away, WKRC-TV reported.

The woman, who identified herself only as Lola, is an American originally from Uzbekistan and said she and the people she was with were "sitting there peacefully and quiet" before getting asked to remove the flag.
"This is not Russia. This is United States of America," she told the station.
Video posted on Twitter showed Lara confronting the fan. Lola told WKRC-TV that the tennis players began playing again for a few minutes before a security guard came up to her.

Western & Southern Open officials said in a statement to Reuters the flag was too large.
"Per the Western & Southern Open's bag policy, as stated on the tournament's website, flags or banners larger than 18 x 18 are prohibited. Therefore, the patron was asked to remove the flag from the grounds and after doing so was allowed to remain at the tournament," a spokesperson for the event said. "Any inquiries about the chair umpire should be directed to the WTA Tour."
