Restrictions continue to ban reporting of his address and where he is detained.

Varybrus stabbed Charlie, who was not known to him, when a fight broke out between them and two other boys on the dancefloor after Varybrus and his friends were asked to leave the party following complaints about his behaviour towards a girl.

While the knife has never been found, witnesses at the party told jurors during the trial that they saw Varybrus “drenched” in blood and heard him say “I’ve stabbed someone” after the attack.

A guest at the party also captured part of the violence on video as she began filming her friends dancing to the song Toxic by Britney Spears under disco lights in the marquee.

Varybrus did not to give evidence in the trial but denied both charges.
