Donald Trump's youngest son contacted UK police saying he witnessed a friend in London being beat up during a video call, a court has heard.

Barron Trump, 19, told police he had friends call 999 from the US to report the alleged attack in January 2025.

Matvei Rumiantsev, 22, is on trial at Snaresbrook Crown Court accused of assault and two counts of rape, among other charges, against the alleged victim, who cannot be named for legal reasons.

He denies assault, actual bodily harm, two counts of rape, intentional strangulation, and perverting the course of justice by pressuring the woman to withdraw her complaints.

Trump called the alleged victim on 18 January last year, the court heard. Shortly after placing the call, he contacted the police, saying she was being assaulted.

I'm calling from the US; I just got a call from a girl, you know, she's getting beat up, he said, according to a transcript of the call released by the Crown Prosecution Service.

When asked by the operator how he knew the woman, he said: I met her on social media, I don't think that matters. The operator responded, asking him to stop being rude and answer questions.

Trump stated he saw a shirtless man with darkish hair before the view flipped to the victim receiving blows while crying, lasting only a few seconds.

Rumiantsev denies the charges, which date between November 2024 and January 2025. Prosecutors allege Rumiantsev strangled the woman the evening of 17 January last year. He claimed their interactions were consensual during a night of drinking.

The trial continues as both witness testimonies and defense arguments unfold, revealing tensions that predated the incident.
