An elderly woman has died after being hit by a cyclist on Oxford Street, central London.
Police were called just before 4.30pm on Tuesday after reports of a collision on the busy shopping street.
The pedestrian, a 73-year-old woman, was taken to hospital with a head injury but died hours later.
Met Police officers say they are keen to hear from witnesses, especially anyone who filmed the collision.
They would also like to hear from anyone who was in the area at the time of the incident or the moments just before it.
Anyone with information is asked to contact the Met’s Serious Collision Investigations Unit on 020 8543 5157.
The cyclist, who stopped at the scene, is not believed to have been badly hurt and has not been arrested.
A Metropolitan Police spokesperson said: “Police were called at 16:29hrs on Tuesday, 12 September to reports of a road traffic collision on Oxford Street.
“At the scene, officers discovered a cyclist in collision with a pedestrian.
“The pedestrian, a 73-year-old woman, was taken to a central London hospital with a head injury. She died in the early hours of Wednesday, 13 September. Next of kin have been informed.”
There is no indication at this stage that the cyclist involved in the incident was in any way at fault for the collision.
However, government minsters have recently hinted that they could tighten laws so that dangerous driving charges can be brought against cyclists. They currently only apply to drivers of motorised vehicles.
It comes after Kim Briggs, a 44-year-old mother of two, was killed in a collision with a cyclist near Old Street, London, last February.
Last month, Charlie Alliston, 20, was convicted of causing bodily harm after it emerged that he had been riding the bike without front brakes.
Theresa May revealed during Prime Minister’s Questions earlier in September that the Government is “looking at” extending the laws on dangerous driving.
