Risaan Udayakumar: Brother detained for killing secret boyfriend
A boy who stabbed his sister's secret boyfriend to death has been detained for seven years.
The 17-year-old - who cannot be named for legal reasons - found Risaan Udayakumar, 18, hiding in the garage at his family home in Watford in July.
He proceeded to stab Mr Udayakumar three times in the heart. A jury found him guilty of manslaughter but cleared him of murder.
The victim's family said the sentence was not "proper justice" for killing.
In a statement, Mr Udayakumar's family said: "We did not wish to attend today's sentencing by way of protest against what we perceive to be a weak legal team, which failed to get proper justice for our innocent son.
"As a grieving family, we feel that a much tougher stance is needed around knife crime to send a stronger message to society."
During the trial at St Albans Crown Court in January, the court heard how the parents of the boy and his 19-year-old sister were away on holiday at the time of the killing but had left strict instructions that she and her brother were not to have friends over to the house.
Prosecutor Michael Speak said the woman had not told her parents about Mr Udayakumar, from Wembley, London, because they had "strict views" about relationships.
On 10 July, the sister met Mr Udayakumar at Watford railway station and they went back to the house together.
Later they heard loud knocking on the door and the sister, fearing her brother's reaction, hid Mr Udayakumar in the garage, where the brother, who was 16 at the time, found and stabbed him.
At a sentencing hearing, Judge Michael Kay QC said the parents "ought to be thoroughly ashamed" about the way they had reacted to an incident some years earlier, when the brother was criticised for "not being strong and macho enough to protect your sister".
Judge Kay said: "To what extent that had an effect on you in July of last year I don't know, but it may have played a part."
He said the brother had come from a "traditional household" where the relationship between his sister and the victim "would not be seen in a favourable light".
"This has led to a situation where you killed another young man who, in every way, was blameless. They were perfectly entitled to be in such a relationship," he said.
