Jackie Hughes had her family “ripped apart” last April when her son Cori Fieldhouse, was arrested for grievious bodily harm and sentenced to three years in Swinford Hall prison.
But the Chelmsley Wood mum has since spoken to numerous witnesses who say Cori had acted to break up the attack being carried out by two other men.
Jackie believes the 20-year-old was targeted by police because of a former GBH conviction in 2007.
“Cori’s no angel, no-one at that age is but he had a job, girlfriend and was moving on with another part of his life.
“But as far as they were concerned, he had previous, they had got their man.
“Once you’re convicted, you’re convicted for life,” she added, breaking into tears.
“I know my son is innocent and he’s had his life ruined for breaking up a fight which could have killed the victim.”
The family are now trying to appeal against Cori’s sentence using witness statements from party guests who were not interviewed originally by police.
“If the police had been doing their job properly, I wouldn’t have to be doing this,” added Jackie, who admitted to attempting an overdose following her son’s devastating sentence.
“When you live in this environment you don’t grass, you expect people to stand up and be a man and admit what they’ve done.
“But no-one ever thought that Cori would get sent down for something he never did. We all thought justice would be done.”
Now Meriden MP Mrs Spelman has agreed to write to the police Chief Superintendent on behalf of the family who are trying to raise thousands of pounds for an appeal.
The family are holding a Free Cori night on March 10 at Kingshurst Labour Club in Clopton Crescent to try to raise the £2,000 needed to take the first step towards an appeal; a Lie Detector test. The evening will include auctions, raffles and a DJ. Tickets are £5 (£7 after 9pm on the door).
