Police is working to trace two men who left a seriously injured female and her young child in the wreckage of their vehicle after crashing into it in a stolen automobile.
Dashcam video footage reveals the black Volkswagen Golf taking a trip at speed down Leeds Road, Dewsbury, when it surpassed a lorry and struck a white Ssangyong Korando, triggering it to spin around.
A 35-year-old woman in the white car was airlifted to hospital with severe facial injuries. Her two-year-old child was not hurt in the 12 July incident.
The suspects then left the spot, West Yorkshire Police said.
