Videos target Andre Agassi

Michael Graf, 55, the brother of former world number one Steffi Graf, has posted Facebook videos in which he claims that her husband, former US tennis star Andre Agassi, physically attacked him. Bild reported the clips, which Graf is said to have recorded while hiding in the tunnel system under Las Vegas. The Daily Mail reported that he had been living in the storm drain network under the city. In the newest video, Graf sits shirtless in front of a wall covered in graffiti, with the concrete of a flood channel above him. Graf does not say why the dispute started or when it took place. Agassi and Steffi Graf have not commented on the claims, which cannot be verified.

Graf's account of the fight

Graf says Agassi enjoyed hitting him as hard as possible, and that he himself provoked Agassi until the situation escalated.

“I really believe Andre enjoyed hitting me as hard as he could.”

Graf also says he hit back, calling it 'a real pirate move', and claims he pinched Agassi's nipples. He says he did so because Agassi no longer wore the pirate earrings that were his trademark in the 1990s, and that otherwise he would have pulled Agassi along by them. Berliner Zeitung noted that earrings were indeed a signature of Agassi's in the nineties. None of these details, including when the alleged fight happened, has been confirmed.

Claims about the family

According to Bunte, Graf's videos also target his own family. He describes an unhappy childhood, says his mother Heidi, 82, favored his sister, and claims Steffi Graf tricked him at card games.

“She tricked me, just to win. That bothered me so much about her.”

Graf adds that Steffi repeatedly humiliated him to the point that he lost his self-confidence. He also says she cared only about herself and their mother. These are personal accusations made by Graf himself and have not been independently verified.

Warrant and court record

Nevada authorities issued an arrest warrant over alleged violations of a court protective order, Bunte reported. The order requires Graf to keep a distance of 100 yards from his wife, Christine, and the same applies to his mother Heidi, who has protection due to stalking. According to Bunte, Judge Melisa De La Garza ordered that Graf remain in custody without bail after an arrest. Focus Online reported that he missed a court date on 30 September. Berliner Zeitung reported that in early 2026 police found him asleep in his wife's garden, and that after that arrest he wore an electronic ankle monitor. Bild reported domestic violence allegations and a drunk-driving arrest in Boulder City, near Las Vegas, in spring 2026, when he was stopped in his Tesla. The presumption of innocence applies.

Where he lives now

Graf had lived in a house near Lake Mead, east of Las Vegas, and filed for divorce from Christine in January, according to Berliner Zeitung. He later lived in his Tesla and then in a tent at Lake Mead. Focus reported that a fire destroyed his camp in August. Polsat Sport reported that he afterwards slept in his car, which he eventually crashed in September. The Facebook videos were recorded in the tunnels, and the date of their recording was not stated in the reporting.
