The rider of the motorbike, a man aged in his 40s, was taken to the John Radcliffe Hospital in Oxford with serious injuries.

Several days after the crash the motorcyclist remains in hospital with serious injuries. 

The driver of the Ford Focus, a woman in her 30s and a nine-year-old child, were also treated in hospital for less serious injuries. Both the driver and the nine-year-old child have been discharged from hospital. 

Tributes have continued to be paid from across the county in the Oxford Mail's book of condolence following the news.

Sophia Howie wrote: “My heart goes out to all the family and friends of this little boy who is only a year younger than my son.

“This really hit home for me. I am lost for words.”

Jamie, who did not provide his surname, added: “Sending the family and friends so much love. I cannot begin to feel your pain but I hope you feel the love and support. RIP little one.”

No arrests have been made as Thames Valley Police has launched an appeal for witnesses following the incident.
