The Met’s Serious Collision Investigation Unit (SCIU) are asking for witnesses to come forward following an accident involving a red Toyota Yaris on the A240 Kingston Road between Tolworth and Ruxley Lane, yesterday Tuesday 14 July at approximately 15.20hrs.

A 44 year old woman was taken to a South London hospital with serious injuries; her condition is critical.

It is thought that a motorcycle was involved in a minor collision with the driver of the Yaris shortly before the serious collision happened further north on the Kingston Road. Officers have spoken with the motorcycle rider.

Police are appealing for witnesses to either of these incidents. Please contact the SCIU via Twitter @MetCC. You can also call 101 and quote CAD6614/14July.
