Tennis legend Steffi Graf’s brother on the run and hiding in Las Vegas tunnels

The brother of much-loved tennis legend Steffi Graf is on the run in Las Vegas and hiding in tunnels.

Michael Graf, 55, has been sharing videos of himself from the city’s famous network of tunnels, which spread 900km and are commonly used by homeless people for shelter.

There is a warrant for his arrest that relates to a misdemeanour charge of trespassing.

Steffi Graf is married to former tennis superstar and high-profile Las Vegan Andre Agassi.

In the videos, Michael Graf can be heard mumbling and ranting, making disturbing claims about Agassi.

“He enjoyed hitting me as hard as he could,” Michael says.

“I mean, that’s understandable. I just kept pushing all sorts of buttons.

“I just thought to myself, what the hell, another idiot?

“I don’t mean to say that her partners are idiots, but I just thought … no, no, no.

“I mean, I really gave him a good whack. It was like… a real pirate move.”

He also says something about pinching Agassi’s nipples because “he wasn’t wearing his pirate earrings anymore”.

“Otherwise, I would have dragged him behind me by his earrings, 100 per cent,” he says.

Michael Graf reportedly had a marriage breakdown this year (his second marriage), left his home, and had been living in his Tesla.

The car, however, was involved in a crash in September.

In one of the videos, there appears to be a shopping trolley full of Graf’s possessions.

The New York Post has reported that there is also an “active warrant” out on Graf “for failing to appear in court” in March following an arrest that month for DUI (driving under the influence) in Boulder City.

In 2014, Steffi revealed that Michael, his four children, and her mother lived with Andre and herself following their wedding.

“Very shortly after my mum moved to Las Vegas, and then my brother and his four kids, so we have all the family there,” she told Hello! magazine.

“All the cousins are together and growing up together ... it’s pretty neat.”

Steffi provided legal support for her brother after an arrest in 2020 for what was described as “violent outbursts”.

After paying legal fees, she also bought him a house.

Agassi is an eight-time grand slam champion and collected all four titles, including four Australian Opens.

Graf won a whopping 22 grand slam singles titles and is the only tennis player to have a “quadruple career grand slam”, winning all four major singles tournaments at least four times.

Her career prize money finished at $21,895,277 while Agassi won more than $31 million (US).

They reportedly have a combined net worth of about $290 million.

The tunnels in Las Vegas were built for flood control following wild flash floods in the 1970s. Flooding occurs because the desert ground around Sin City is so baked and hard that rainwater just runs off it, unable to penetrate.
