The 18-year-old defender, who has been at the club since 2003 and has represented England Under-17s, caused a crash which killed two people and injured two more in September
The 18-year-old was behind the wheel of his Mercedes speeding at 56 miles per hour in a 30mph zone when he crashed into a Nissan Micra emerging out of a side street, killing both Kulwant Singh, 32 and his 37-year-old sister, Ravel Kaur, in the front seat.
The two victims originally came to the United Kingdom in 2001 after fleeing persecution from the Taliban. Ms Kaur's two sons, aged 16 and 17, were also both injured in the collision while in the back seat of the vehicle, from which they are still recovering.
Meppen-Walter, who was given a driving ban of three years shortly after the incident took place in September of last year, pleaded guilty to two counts of casuing death by dangerous driving at Manchester Crown Court.
The City youngster had previously represented England at Under-17s level.
