Director of Public Prosecutions Renson Ingonga has asked a Nairobi court to order the extradition of Brian Kiprop Kiplagat to the United Kingdom, the Daily Nation reported. Kiplagat is wanted over the alleged murder of his girlfriend, a fellow Kenyan. The offence allegedly took place in Woolwich, in the Borough of Greenwich, between January 12 and 28, 2025.
Principal Magistrate Caroline Mugo of the Milimani Law Courts heard that the Westminster Magistrates' Court has issued warrants against Kiplagat on eight counts. They are murder, manslaughter, two counts of perverting the course of justice and four counts of fraud by false representation.
The prosecution said the extradition court only has to confirm the suspect's identity and decide whether the request is political. In its view, the court should not weigh the evidence or the merits of the murder case. Those questions belong to the courts where the offences allegedly happened. Prosecutors said that after the alleged crime, the suspect "escaped back to Kenya". They told the court that his rights and healthcare are protected and that property not needed as evidence will be returned.
The prosecution said Kiplagat's mobile phone is key evidence. It is being held under a mutual legal assistance request from British authorities. Kiplagat, who has no lawyer, opposed the extradition request and challenged the phone's retention. He told the court that the UK extradition file contains no request for Kenya to investigate or hold the device.
Kiplagat also asked to be taken to collect his identity card. The magistrate declined to authorise an immediate visit. She told the investigating officer to first confirm independently that the card is ready. The court would then give directions on its collection, which could include an escort.
Kiplagat was arrested on June 10, 2026, at the Namanga border post. He was trying to cross into Tanzania on a temporary travel permit. At an earlier hearing, prosecutors said he had no fixed address in Kenya and had been moving between locations. They said he was carrying several travel documents, some suspected to have been obtained fraudulently.
Kilonzo was 43 and had worked at Citi for more than 18 years. She moved to London in 2023. Her body was found at her flat in Woolwich, south-east London, on January 17, 2025, after concerns were raised about her welfare. A post-mortem concluded that she died from blunt force trauma to the head.
