A dad has launched a desperate plea after his teenage son was left for dead in a hit-and-run.
Harvey Aitken, 16, was cycling in Tyseley in Birmingham when he was involved in a collision in July, leaving him with a bleed on the brain.
The teenager spent three weeks in hospital after he sustained serious injuries and has since struggled with a speech impediment and memory loss.
Doctors said Harvey could take up to two years to fully recover due to the seriousness of his injuries.
Harvey's dad Andrew has launched a public appeal for information, saying the incident has had a "profound impact on his life".
West Midlands Police have also launched an urgent investigation and are trying to identify two cars involved in the incident.
Officers believe one car hit the teenager at 11.35pm on 9 July along Wharfdale Road before a second car stopped and flashed its headlights.
Officers are appealing for information regarding the driver of the second car, a Ford Focus, as they believe they will be able to explain what happened.
Andrew said: "Harvey has suffered a severe brain trauma as a result of this hit-and-run and we have been told it will take up to two years for him to fully recover.
"When I received the phone call at 3am that morning my heart sank, it is every parents’ worst nightmare.
