(CNN) — One of the men believed by police to be involved in an attack on V. Stiviano, whose tape recording of Donald Sterling ranting against African-Americans led to his NBA lifetime ban, surrendered Tuesday to police, a New York Police Department official familiar with the investigation told CNN.
Police had interviewed the 40-year-old Long Island man at the time of the incident Sunday, the police official said.
The development comes a day after Stiviano filed a formal police complaint in the alleged assault outside a New York hotel.
Stiviano says two men followed her yelling racial slurs, then punched her several times. The blows left the right side of her face red and swollen, he said.
“We understand that there are now two videos of the assault that have been located,” her lawyer’s office said in a statement. “In addition, several witnesses have been come forward with relevant and critical information regarding the facts surrounding the incident and the identity of the assailants.”
The assault took place as Stiviano was leaving a restaurant by the Gansevoort Hotel with her sister and friends.
It also came after video surfaced on TMZ that showed Stiviano making disparaging remarks about African-Americans. “I don’t understand black people. You give them a little bit of money, they don’t know what to do with it,” she says in the video that purportedly dates back to 2011 as part of a reality show pilot, TMZ said. CNN reached out to her attorney, Mac Nehoray, for comment on the video but has not received a response.
Earlier, Stiviano recorded inflammatory remarks by Sterling, owner of the Los Angeles Clippers basketball team, which spawned outrage among NBA fans, players and executives.
In the recording, Sterling chastises Stiviano for posting pictures online of herself with African-Americans, including NBA legend Earvin “Magic” Johnson. He tells her not to bring Johnson to Clippers games.
NBA Commissioner Adam Silver banned Sterling from the league, fined him $2.5 million and pushed through a charge to terminate all of his ownership rights in the franchise.
