A 22-year-old Russian man has been convicted of assault in a London courtroom after Barron Trump, the youngest son of President Donald Trump, witnessed the attack during a FaceTime call and immediately contacted British police.
Matvei Rumiantsev was found guilty at Snaresbrook Crown Court of assaulting a woman he had been dating. The conviction followed testimony that the 19-year-old Trump placed an emergency call to London authorities after seeing the woman being struck during a late-night video conversation from the United States.
The incident occurred on January 18, 2025, when Barron Trump attempted to FaceTime the woman, whom he had met on social media. When the call connected at 2:23 AM local time, Trump said he was startled to see a bare-chested man answer instead. The camera then flipped to show the woman crying and getting hit while stating something in Russian, according to testimony presented in court.
The FaceTime call lasted only 10 to 15 seconds before it was hung up. Trump immediately dialed emergency services to report what he had witnessed. A recording of that call was played during the trial, capturing Trump’s urgent attempts to get help for his friend.
“I don’t think these details matter, she’s getting beat up,” Trump told the dispatcher during the exchange.
London police responded to the address Trump provided and arrested Rumiantsev, a receptionist who lived in New Providence Wharf, east London. The woman later testified in court that Trump’s intervention helped save her life, according to reports from the proceedings.
During the trial, prosecutors presented evidence that Rumiantsev had been in a relationship with the woman for about six months. Testimony indicated that Rumiantsev was jealous of the woman’s friendship with Barron Trump. Rumiantsev himself testified that he felt badly for Trump because he thought his girlfriend was leading him on.
The jury convicted Rumiantsev of assault and also found him guilty of perverting the course of justice. The second conviction stemmed from a letter Rumiantsev sent from jail asking the woman to retract her allegations against him.
However, the jury acquitted Rumiantsev of more serious charges. He was found not guilty of rape and choking the woman on the night Trump called police. He was also acquitted of an additional rape and assault that allegedly occurred in November 2025.
Defense lawyer Sasha Wass challenged the reliability of Trump’s account during the trial. She questioned how much the president’s son could have actually seen during what she described as five or seven seconds of video. Wass argued that Trump didn’t know the woman had a boyfriend and suggested the woman exploited her ties to Trump to make her boyfriend envious in what the defense characterized as a relationship full of dramas.
Barron Trump, the only child of Donald and Melania Trump, did not testify in the case. His absence from the witness stand became a point of discussion as Justice Bennathan addressed the jury before they began deliberations.
The judge advised jurors to treat Trump’s accounts with caution because he hadn’t been subjected to cross-examination. These accounts included both the recording of his call to the police and a follow-up email he sent to investigators.
The case highlights the increasingly complex nature of international emergency response in the digital age. FaceTime and other video calling platforms have created situations where witnesses to crimes can be thousands of miles away from where incidents occur, raising questions about jurisdiction, evidence reliability, and the challenges emergency dispatchers face when receiving calls from overseas.
The involvement of a member of the first family in a foreign criminal case also presents unusual diplomatic and security considerations. While Barron Trump was an adult at the time of the incident, his status as the president’s son adds layers of complexity to what would otherwise be a straightforward witness situation.
The trial took place on January 20, 21, and 22, 2026. Rumiantsev is scheduled to be sentenced on March 27. The court will determine the appropriate punishment for the assault conviction and the separate conviction for attempting to pervert the course of justice.
British courts treat witness tampering seriously, particularly when defendants attempt to influence victims or witnesses from custody. The letter Rumiantsev sent asking the woman to retract her allegations demonstrated what prosecutors argued was a continuation of his efforts to control and manipulate her even after his arrest.
The case has drawn significant media attention both in the United Kingdom and internationally, with coverage appearing in outlets ranging from tabloids to major news organizations. The unusual circumstances of the case, combined with the involvement of the U.S. president’s son, have made it a subject of widespread public interest.
Neither the Trump family nor the White House has issued public statements about Barron Trump’s role in the case. The younger Trump has largely remained out of the public eye, and his involvement became known only through the court proceedings in London.
The woman’s identity has been protected throughout the legal proceedings, as is standard practice in British courts for alleged victims of sexual assault and domestic violence.
