Police have appealed for witnesses after a woman was killed following a collision involving a car towing a trailer in west London yesterday.

The fatal crash happened on Warwick Road, Earls Court at around 3.45pm yesterday afternoon, with the 68-year-old victim pronounced dead at the scene. Her next of kin have been informed.

The Metropolitan Police said that the driver of the car stopped at the scene but was not arrested.

Police have asked anyone who witnessed the incident to contact the Serious Collision Investigation Unit witness line on 020 8543 5157.

One Twitter user who arrived at the scene after the incident tweeted a picture of the vehicle involved, a white Range Rover with a large trailer attached.

Yesterday’s fatality was the fourth cycling death in the capital this year, the other three all happening in south east London.

Earlier this month, 52-year-old Antonio Marchesini was killed in Deptford while riding on Quietway 1, with the driver of the car involved fleeing the scene and later arrested by police.

In May, two cyclists, Edgaras Cepura, aged 37, and Oliver Speke, 46, were killed in separate incidents involving lorries on the same stretch of road in the Royal Borough of Greenwich.

Those deaths led to the campaign group Stop Killing Cyclists holding a vigil and die-in outside Greenwich Council’s offices in Woolwich the week before last.
