A Russian man convicted of assaulting a woman in London in an attack witnessed by Barron Trump, President Donald Trump’s youngest son, on a video call was sentenced to four years in prison by a London court on Friday. 

Matvei Rumiantsev, 23, an MMA fighter, was convicted by a jury on Jan. 28 of assault with bodily harm but was acquitted of rape and choking charges. He was also convicted of perverting the course of justice stemming from a letter he sent the woman from jail asking her to retract her allegations.

After the assault, Rumiantsev admitted he was jealous of his girlfriend's friendship with the 19-year-old son of President Donald Trump.

"Your lack of insight and empathy was apparent at trial," Justice Joel Bennathan said. "You continue to try to blame the complainant for everything that has happened."

Trump told investigators he had placed a late-night FaceTime call to the woman, whom he had met on social media, and had been startled when the call had been briefly answered by a shirtless man on Jan. 18, 2025.

"That view lasted maybe one second and I was racing with adrenaline," Barron Trump said. "The camera was then flipped to the victim getting hit while crying, stating something in Russian."

Barron Trump called the police in London.

"It’s really an emergency … I’m calling from the U.S., uh, I just got a call from a girl, you know, she’s getting beat up," he told an operator. 

Police responded to the address and arrested Rumiantsev, a London-based receptionist.

At his trial at Snaresbrook Crown Court, Rumiantsev was acquitted of rape and choking related to the attack, as well as a separate rape and assault allegation from November 2024.

His attorney, Sasha Wass, said that Trump wasn't aware the woman had a boyfriend and questioned how much he could have seen in just a few seconds of video. 

Trump never testified in the case. However, the judge praised him for his quick-thinking actions. 

"Mr, Trump properly and responsibly, despite being in the United States, made sure the emergency services here were called, and he told them what he had seen," he said.

Two foster children who had been living with a convicted transgender triple killer, despite authorities being aware of the situation since late December 2025, are no longer residing with the violent criminal, according to local media reports.

Reginald Arthurell — who began transitioning to a woman shortly after his release from prison in 2020 — was removed from the home after heavily armed officers raided the address on Monday, radio station 2GB reported. He had been living with a 12-year-old and a 14-year-old for several months, the outlet said. 

The minister for Families and Communities of New South Wales (NSW) on Tuesday issued an apology, saying the situation "should never have been allowed."  

"It is entirely unacceptable for a vulnerable child in the care of the state to be living with a triple murderer," Kate Washington told 2GB. "It should never have happened and I'm deeply apologetic for what has happened."

She added that "very poor decisions were made" at the time when authorities became aware of the situation and said a review is underway to determine how the "terrible" circumstances were allowed to happen, promising systemic changes.

The situation has sparked widespread backlash and calls for the resignation of authorities who allowed the crisis to continue for months. 

Late last year, Arthurell moved into an existing foster home in Sydney, where two children were already living under the care of an elderly woman, 2GB reported. He reportedly met her while she was working at a hospital, and he was a patient there.

The woman, who invited him to move in as a housemate, already had two foster children living with her under her approved placement with the New South Wales Department of Communities and Justice.

Arthurell therefore shared the household with the children. The arrangement went unnoticed by authorities until the carer’s daughter reportedly raised concerns late last year.

Prior to moving in, Arthurell had built a long criminal history, primarily involving the killings of three people over three decades, court documents show. He was first convicted of manslaughter in 1974 for reportedly stabbing his stepfather to death in Sydney. In 1981, he fatally bashed a 19-year-old sailor during a violent robbery, and while on parole in 1995, he killed his fiancée by beating her to death with a piece of wood, local outlets reported.

After killing his romantic partner, he was caught photographing himself wearing one of her dresses, 2GB added.

All three killings involved alcohol, court documents show. Records indicate that Arthurell spent nearly 39 years of his life in custody following the murders.

After his prison release in November 2020, Arthurell began transitioning into a woman under the name Regina. The first public photos and self-introductions appeared on a transgender community Facebook page in May 2021, 2GB reported. Arthurell had also expressed plans to undergo gender-affirming surgery "as soon as possible," News.com.au reported.

Court documents also described that "her transition has been taking place over quite some years," confirming the process was ongoing after his release.

Arthurell now remains in private accommodation following his Monday removal, ABC Australia reported Tuesday.
