A mother-of-two in Britain has pleaded guilty to causing the death of an 11-year-old boy by dangerous driving.

Hannah Saaf knocked down and killed Sam Riddall as he walked home with a group of friends from a church youth service in Westbury-on-Trym, Bristol, on May 1.

Saaf's white Ford Focus estate car was said to have careened off the road and mounted the pavement before hitting the group.

The mother of twins immediately bolted from the scene, leaving her car and Sam behind.

As the 27-year-old fled, doctors at Bristol Royal Infirmary desperately tried to resuscitate the boy but their efforts were in vain.

During the hunt for Saaf, which took nine gruelling days, Sam's parents, Martin and Rachel, made a heartbreaking televised appeal for Saaf to turn herself in.

Riddall, 39, fought back tears as she said: "I am here to appeal to Hannah as a mum, who has lost a precious son.

"Please come forward, Hannah, and talk to the police so we can begin to put our lives back together."

Officers arrested Saaf on May 10 after she was found sleeping in a barn in the village of Publow, near Bristol — some 10 miles from the scene of the crime.

She was held at a police station in Bristol and charged with causing death by dangerous driving, failing to stop and/or report an accident, driving otherwise than in accordance with her licence and driving without insurance.

Saaf, of St. Michael's Hill, Bristol, was dressed in a grey pinstripe suit and appeared calm as she entered her plea today at Bristol Crown Court.

Sentencing was adjourned to Nov. 27 for psychiatric reports to be prepared.

Defending counsel Ian Kelcey said Saaf "was undergoing inpatient treatment at a mental health establishment".
