The parents of teenage murder victim Ben Kinsella have said they are "completely devastated" that the father of one of his killers has apparently received a five-figure pay-out from police.
Debbie and George Kinsella said it was "unjust and unfair" that the amount reportedly given to Michael Alleyne senior was double what they received after their son's death.
The couple were paid £10,000 after 16-year-old Ben was stabbed to death in June 2008 when a fight in a bar spilled out on to the streets in Islington, north London. But the Sunday Mirror reported that Mr Alleyne, whose son Michael Alleyne junior was convicted of Ben's murder in 2009, had received £20,000 after he was injured in a police raid.
The newspaper said that Mr Alleyne senior was injured when officers searched the flat looking for his son, and his dog was also hurt.
Ben's mother Debbie told ITV's This Morning that her family are "very angry, extremely upset. We feel let down, we've spent the weekend crying. We're just completely devastated".
Ben's father George said: "We would like to see a balance where each case is treated on equal terms. That money that we got just about paid for our son's funeral. Really, it's not about the money, it's about the principle of it all. It's not just our family, it's all the victims of knife crime and violent crime, and the law is so unjust and unfair."
The couple were told last summer that Mr Alleyne was taking legal action but said they did not believe it would be successful.
Mrs Kinsella said: "We were told about it and we just didn't think it would happen to be honest. We thought there wasn't a case to answer and it would be thrown out of court.
"It's like a slap in the face, we struggle every day. It was reported Mr Alleyne senior has nightmares: well what does he think we do? We're talking about murder, my son was murdered, and I feel that he's benefited from my son's murder."
A Metropolitan Police spokesman said: "We are aware of the claim lodged in the High Court following an incident in N7 on August 30 2008. The claim was settled and a sum paid. We are not prepared to discuss further. We do not disclose the amounts of awards following civil claims."
