A man has been arrested on suspicion of murdering a 22-year-old woman who was stabbed to death in a taxi.
West Midlands Police said the 28-year-old man, named by sources as Junior Saleem Oakes, was was found in the garden of a house on Allens Farm in south Birmingham just after 6pm on Tuesday.
The suspect, also known as Mohammed Saleem (Salim) Junior Oakes, has been taken to a police station in the West Midlands for questioning, a force spokesman said.
The victim, who has not been named, was knifed repeatedly while still in the car in Northfield, Birmingham, at around 8am on Tuesday.
A police spokeswoman said the taxi driver called 999 from the scene, on Dimsdale Road, but the woman was in cardiac arrest when paramedics arrived and could not be saved.
Detective Chief Inspector Wayne Jones described the police investigation as "complex and dynamic" and renewed earlier appeals for witnesses to come forward.
A post-mortem examination is expected to be conducted on Wednesday.
