A United Nations judge studying for a PhD in law at the University of Oxford has been convicted of forcing a young woman to work as a slave.

Prosecutors said Lydia Mugambe, 49, took “advantage of her status” by preventing the woman from holding down steady employment and forcing her to work as her maid.

Following her conviction on Thursday, Thames Valley Police released bodycam footage showing Mugambe’s arrest at her home in Oxfordshire.

In the footage, Mugambe appeared shocked when an officer said he was arresting her under the Modern Slavery Act.

She told the arresting officer: “I am a judge in my country, I even have immunity. I am not a criminal.”

Asked to reaffirm that she had immunity, Mugambe said: “Yes, I have a diplomatic passport.”
