The family of Yousef Makki have unveiled a 'vandal-proof' plaque at the scene where he was stabbed to death.
The tragic teen's sister Jade and her husband Mazen Akoum said the poignant memorial would 'celebrate Yousef's memory and remember his final resting place.'
The plaque has been attached to a tree which is 'symbolic' to the Makki family and supporters and will remain 'a shrine to Yousef and his role as a peacemaker on the night he died', they said.
Previous tributes left at the scene in Hale Barns have been removed, it has been claimed.
Former Take That manager and local resident Nigel Martin-Smith said has worked with the local council to get the permanent plaque installed.
Yousef was stabbed to death by Joshua Molnar on March 2, 2019.
Molnar, from a wealthy Hale family, was found not guilty of murder and manslaughter following a trial at Manchester Crown Court in 2019, telling the jury he had acted in self-defence.

Now 20, he repeated the evidence he gave at trial, explaining to the inquest into the death last month that Yousef had called him 'p*ssy', pushed and punched him during a clash, saying he wasn't sure who had pulled a knife first.
Senior South Manchester Coroner Alison Mutch recorded a narrative verdict following a seven-day inquest at Stockport Coroners' Court, saying she could not safely conclude that the death was either unlawful or accidental.
Nigel Martin-Smith said: “It's very sad. Someone appears to be removing tributes to Yousef that have been placed near his final resting place - so I have liaised with the local council and we have produced a vandal-proof memorial plaque which has been placed on the tree where Yousef collapsed and died on that fatal night".
Martin-Smith added: "The incident in which Yousef was killed started close to my property and it has left many people shocked who live in the area."
