Barron Trump played a key role in helping British authorities secure a conviction against a man accused of brutally attacking his former girlfriend in London, after witnessing part of the assault unfold during a late-night video call.
According to The Associated Press, The suspect, 22-year-old Matvei Rumiantsev, a Russian national living in London, was found guilty this week of assault and attempting to interfere with justice following a trial in East London. His conviction stems from a violent incident in January 2025, where Barron, the youngest son of Donald Trump, unexpectedly witnessed it while in the United States.
According to court proceedings, Barron, who was 18 at the time, had connected with the woman on social media and remained in contact with her. One night, he received a FaceTime call that was initially answered by a shirtless man later identified as Rumiantsev.
Barron told authorities the call lasted only seconds, but in that brief moment, he saw the camera turn toward the woman as she was being struck and heard her crying while speaking in Russian. The call abruptly ended, prompting Barron to immediately contact London police.
In a recording of the emergency call, Barron can be heard urgently asking for help while the dispatcher questioned him about how he knew the victim.
“I don’t think these details matter, she’s getting beat up,” Barron said during the exchange.
Police were dispatched to the provided address and arrested Rumiantsev shortly afterward. During the trial, prosecutors said Rumiantsev attacked the woman out of jealousy, believing she was too close to Barron. Rumiantsev himself reportedly admitted that he felt insecure about their friendship and claimed the woman had given Barron the wrong impression about their relationship.
While Rumiantsev was cleared of more serious charges, including rape and choking, the jury found him guilty of assault. He was also convicted of attempting to obstruct justice after sending the victim a letter from jail urging her to withdraw her accusations. Rumiantsev is scheduled to be sentenced on March 27.
Barron did not testify in court, but jurors were instructed to carefully consider his statements made in recordings and written correspondence with investigators, since he was not cross-examined.
Defense attorneys argued that Barron may not have seen the incident clearly in the brief video call and suggested the woman used her connection with him to provoke jealousy. However, the jury ultimately sided with prosecutors on the assault and interference charges.
