A 73-year-old woman has died after being struck by a cyclist on London's Oxford Street.
The pedestrian suffered a head injury in the crash, which happened at about 16:30 BST on Tuesday.
She was taken to a central London hospital but died in the early hours of Wednesday.
A spokesman for the Metropolitan Police said the cyclist stopped at the scene of the crash.
A man was arrested at the scene on an unrelated criminal damage charge. Police have refused to confirm if he was the cyclist.
Roads in the area were closed for several hours following the crash.
Two pedestrians were killed in collisions with cyclists across the UK in 2015.
In 2014 there were six fatalities due to collisions with cyclists.
