The Metropolitan Police is being sued for damages after an officer was fined for using a patrol car to pin a teenager to a wall.
Sherman Thomas fractured his right leg
Sherman Thomas' right leg was fractured after he was chased for allegedly stealing a moped in Brixton, south London in 2000.
The un-named officer was fined 13 day wages but not suspended.
A protest was held outside Brixton Police station on Tuesday by Mr Thomas' supporters who want the officer sacked.
Mr Thomas, who was 18 at the time, wants to meet the panel to express his anger and disappointment.
On 26 July, 2000, Mr Thomas, of Lewisham, south-east London, was found running through the streets after abandoning the moped.
It was stolen but he claims he did not know that and has never been charged with stealing it.
He was pursued by a police car and the vehicle stopped with the wheels against the kerb.
Mr Thomas claims he had hands up but the officer said he was worried he was going to run off, or hit a female officer with a helmet he had in his hand.
This has been denied by Mr Thomas' solicitor.
The car then moved forward, pinning him against the wall.
Mr Thomas said: "The police deliberately attacked me, and covered up from the beginning. From that day I said I wouldn't stop fighting until I got justice.
"They took three-quarters of my life away - I can never get a job now where I have to stand on my feet."
The disciplinary panel found the officer guilty of being "neglectful in the performance of your duties in that you used a police vehicle as a moving barrier in a way that caused severe injury to Sherman Thomas when neither police officers nor any member of the public were confronted by a life-threatening risk justifying such an action."
But the Crown Prosecution Service says there is not enough evidence for a criminal prosecution, so the family have decided to take civil action.
A Metropolitan Police spokesman said: "We received a civil claim in relation to this incident and it would be inappropriate for us to discuss the matter."
