The boyfriend of a Citibank boss who was found beaten to death in her flat in London has been arrested after more than a year on the run.

Marianne Kilonzi, 43, who was vice president of trade and working capital sales at Citibank, was found dead in her home in Woolwich on January 17 last year. 

Brian Kiprop Kipglagat - who was the subject of a 16-month international manhunt - was detained by immigration officers on June 10 as he attempted to enter Tanzania from Namanga, a southern Kenyan border town. He is now facing extradition to the UK in connection with her death.

Kipglagat attempted to travel to Tanzania on a temporary permit, but his movements were being tracked by undercover officers in Kenya at the request of UK police.

The Metropolitan Police were called to Ms Kilonzi’s address following a report of concerns for her welfare.

Blunt force trauma and head injury were given as the cause of death at a post-mortem examination.

The force said at the time that officers believed Ms Kilonzi knew her attacker and that one line of inquiry was that the suspect had fled the country. 

Following her death, a Citibank spokesperson said: "We are deeply saddened by the tragic loss of our colleague. Our thoughts are with Marianne’s family and friends during this difficult time."

Kenyan prosecutors are understood to be awaiting a formal extradition request from UK authorities. Mirror
