A teenager has been badly injured and left with tyre marks on his body after a hit-and-run.
Dominic Evans, 18, was hit somewhere between Craylands Lane in Swanscombe and Knockhall Road in Greenhithe.
The former Swan Valley schoolboy also suffered head injuries and knocked unconscious.
Dominic's mother Donna Shrubsole, who believes the injuries were caused by a moped, said: "His clothes were ripped and he had tyre marks on his groin and thighs.
"Someone has to know who did this. If you have any information please contact the police.
"My son came off lucky but it may be a different story for someone else."
A police spokesman said: "Police are investigating following a fail to stop collision.
"An 18-year-old suffered injuries in the incident and was taken to hospital. Enquiries are ongoing."
Witnesses or anyone with information about the hit-and-run - at just after 10.30pm last Wednesday - are asked to phone police on 101.
