Police have reported the re-arrest of a man accused of murdering his girlfriend in Boston, who had fled to Kenya and escaped from a Nairobi police station nearly a week ago.

Kevin Kinyanjui Kang’ethe, 42, was apprehended on Tuesday at a relative’s residence in Ngong, a suburb of the Kenyan capital, following a tip-off, according to Nairobi police chief Adamson Bungei speaking to CNN.

Bungei assured that Kang’ethe is now in custody at a different police station and that his extradition process to the United States will proceed.

US investigators allege that Kang’ethe boarded a plane to Kenya shortly after the murder of his girlfriend, Margaret “Maggie” Mbitu, on November 1, 2023. Mbitu's body was discovered in Kang’ethe’s SUV in a parking garage at Boston Logan International Airport two days after she was reported missing.

Bungei described Kang’ethe’s escape from a heavily guarded Nairobi police station last Wednesday as a consequence of "unethical conduct."

According to police reports, Kang’ethe fled "by running away" after a man claiming to be his lawyer arrived at the station seeking to speak with him. Officers released Kang’ethe from his cell and left them alone in an office, from where he escaped.

Kang’ethe had previously been arrested outside a nightclub in Nairobi on January 30. After a US extradition request, Kenyan authorities initiated the formal extradition process to return him to Boston to face murder charges.
