A deaf teenager was pushed from his bike into the path of a car in Shrewsbury.
It happened as the 15-year-old was cycling on Lancaster Road just before 1800 BST on Wednesday.
Police say he narrowly missed being seriously injured.
The boy was shaken, but unhurt.
Officers are appealing for the driver of a black Ford Focus who stopped to help the teenager to come forward.
Anyone with any information is asked to contact Shrewsbury Police.
