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 so that he could 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.

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, who cannot be named for legal reasons, on 18 January last year, the court heard.

Shortly after placing the call, the US president’s fifth child contacted the police and said she was being assaulted.

“I’m calling from the US, uh 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.

“This was happening about eight minutes ago. I just figured out how to, how to call someone. Uh, uh it’s really an emergency.”

When asked by the operator how he knows the woman, he said: “I don’t think these details matter, she’s getting beat up but okay fine, also I met her on social media, I don’t think that matters.”

The operator responded: “Can you stop being rude and actually answer my questions?”

Trump was later asked by police to provide a witness statement and said in an email on 2 May that what he saw had been “very brief indeed but indeed prevalent”.

He said he had not expected his call to the woman be answered because of the time difference, but that it was picked up by “a shirtless man with darkish hair”.

“This view lasted maybe one second”, he said, adding the view then flipped to the victim getting hit while crying.

“This whole interaction had lasted 5 to 7 seconds.”

He continued: “I made two of my friends call the Met Police in the UK, even though they are in the US.

“As per evidence I do not have any, I was told by the victim who I am very close with that this individual was giving her difficulty for a long time.”

Rumiantsev denies the charges, which date between November 2024 and January 2025.

On Thursday, the Russian national told the court that he learned about the woman’s friendship with Trump in October 2024 – when she asked him to take a photograph of a chat between them on her phone.

Jurors heard that he and the alleged victim had an argument at her flat in November 2024, in which Rumiantsev damaged her air fryer and dropped her kettle before leaving the apartment.

He said he called the police after receiving calls and messages from her, which made him concerned for her welfare.

The court heard in bodyworn footage, the woman can be heard telling officers: “It was like jealousy, controlling of like who I can be friends with.”

Rumiantsev confirmed in court that she had been referring to Barron Trump, and that she had showed him messages between them earlier that evening.

“I started to explain that I felt upset as well about her talking to Barron Trump,” jurors heard.

“I was in no way controlling but I was trying to make her know that if she feels unwell seeing messages I had with girls 10 years ago, she could maybe understand how I felt when she was sat there this moment texting someone else.”

He later told her in a text message: “I’m very ashamed that I grabbed your phone, you started calling him sweetheart, I felt so unwell.”

The trial continues.
