Patients at the GP surgery where Connor Brown worked have left touching tributes to the 'happy and smiley' 18-year-old.
Connor died following an incident behind The Borough in Vine Place, Sunderland city centre, in the early hours of Sunday.
He was rushed to the RVI for treatment but sadly passed away.
Dozens of tributes have been left in the city centre where the GP receptionist was fatally attacked.
Now patients at Happy House Surgery, where the popular teenager worked, have left floral tributes outside the Durham Road practice.
One tribute outside the GP surgery said: "RIP Connor. Although we didn't know you personally we did know you as the happy, smiley receptionist from the doctors. You helped my mam hold my son when he needed bloods doing.
"You were always smiling."
Another reads: "Connor, always such a kind, helpful and considerate chap. So very sorry this has happened to you and your family.
"Saying prayers for you and all those close to you."
Friends of Connor have announced that they will hold a balloon release event on a field next to North Moor Lane in Farringdon tomorrow.
The balloons are set to be released at 6.30pm.
