A 17-year-old who caused a crash in which a pregnant teenager was seriously injured has admitted driving offences.
The defendant was being followed by police on the wrong side of the A47, near King's Lynn, Norfolk, on 14 January when the incident happened.
At King's Lynn Magistrates' Court he admitted dangerous driving, driving while disqualified, driving without insurance and failing to stop.
The youth was released on bail and sentencing adjourned until 8 March.
The police vehicle involved in pursuing the car being driven by the 17-year-old was in collision with another car travelling on the correct side of the road.
A 16-year-old pregnant girl in the car suffered serious injuries.
Stacy Ellington, who lives near King's Lynn, lost the child she was carrying as a result of her injuries.
The Independent Police Complaints Commission has ordered an investigation into the police's involvement in the incident.
That investigation is being carried out by a senior officer from Suffolk Police.
