Vickrum Digwa, who murdered Henry Nowak, has had his prison sentence increased after the Court of Appeal ruled it was “unduly lenient”.
Digwa will now serve 25 years behind bars after he tried to appeal his original 21-year sentence.
He had argued the initial sentence was “manifestly excessive”.
Mr Nowak, 18, was stabbed multiple times by Vickrum Digwa in Southampton on December 3 last year, who then lied to the police, claiming that his victim had racially abused him.
Digwa “repeatedly deployed” a knife against an “unarmed and defenceless stranger”, the Court of Appeal was told.
In written submissions on behalf of the Attorney General, Jonathan Polnay KC said that Digwa “abused the privilege” afforded to Sikhs to carry a knife in a public place for religious reasons.
He said: “The offender was carrying a substantial bladed weapon in public, immediately available for use, which he repeatedly deployed against an unarmed and defenceless stranger.
“He abused a statutory religious exemption permitting him to carry that weapon.”
“There were significant additional aggravating factors: the offender’s sustained attempts to pervert the course of justice, his false allegation of racism against the deceased, his procurement of his mother’s assistance in concealing evidence, his degradation of the dying victim by filming him, and his conduct in misleading responders.”
“The minimum term imposed failed adequately to reflect the combined weight of those features,” Mr Polany wrote.
Digwa’s mother, Kiran Kaur, may still be released as early as December, having served less than half of her three years behind bars.
Kaur received the sentence for disposing of the weapon used to kill Henry in the aftermath of the crime
