A Kenyan national faces extradition to the United Kingdom after a Nairobi court on Friday endorsed two arrest warrants issued by Westminster Court, clearing the legal path for proceedings that could see him tried abroad for the murder of his girlfriend in London.
The Director of Public Prosecutions (DPP) appeared before the Milimani Law Courts seeking recognition of the UK warrants against Brian Kiprop Kiplagat, who is wanted to answer charges of murder, manslaughter, perverting the course of justice, and fraud by false representation.
Magistrate Bosibori Nyangema allowed the DPP’s application, formally endorsing the Westminster warrants and setting the extradition process in motion under Kenyan law and international legal cooperation frameworks.
“Bosibori Nyangema allowed the DPP’s application to endorse two warrants of arrest issued by the Westminster Court, paving the way for the commencement of the extradition process in accordance with Kenyan law and international legal cooperation frameworks,” the Office of the DPP stated.
The prosecution also successfully opposed Kiplagat’s release on bail, leaving him remanded in custody. The matter returns to court on Monday, June 29, 2026, when further directions on the extradition proceedings will be issued.
The case stems from the death of Marianne Kilonzi, a Kenyan banker, who was found dead in her South London apartment in January 2025. Investigators discovered her body with a severe head injury in a pool of blood. Kiplagat, identified as her boyfriend, reportedly left the UK shortly after the incident, prompting Westminster Court to issue a warrant for his arrest.
Authorities tracked him across several countries. Passport records showed he had moved through France, Uganda, and Kenya before he was arrested on June 10 at the Namanga border while allegedly attempting to cross into Tanzania. He was found in possession of two passports and a travel visa that linked him to the deceased.
He was subsequently detained at the Anti-Terrorism Police Unit for seven days as investigations continued. He had challenged his continued detention, arguing that no formal extradition request had been filed, but the court found sufficient grounds to hold him, noting he posed a flight risk.
The prosecution team handling the matter is led by Senior Deputy Director of Public Prosecutions Vincent Monda, assisted by Victor Owiti, Magdalyne Nduati, and Brenda Nandwa.
The Kenyan courts will now determine whether Kiplagat should be surrendered to the UK to stand trial on the charges listed in the extradition request.
