A teenager is due to find out on Thursday whether he will need plastic surgery, after being set alight in an unprovoked attack.
Mark Burdis suffered serious burns in the attack
Mark Burdis, 17, suffered serious burns to his face, neck, chest and hands, after a burning liquid was thrown at him.
From his hospital bed on Tyneside, the teenager condemned his attackers as "having no remorse" as they watched him roll on the ground trying to extinguish flames.
Police say Mark was making his way home through the Quayside area of Newcastle on Monday, after a night out with two friends, when the incident took place.
At about 2300 BST on Monday they reached the New Redheugh Bridge road by the Telewest arena, when they saw smoke coming from nearby bushes and went to investigate.
After speaking briefly to a group of four or five male youths, they turned to walk away when Mr Burdis was hit by an object that set him alight.
Mr Burdis said: "They had no remorse or feelings and just watched as I burned.
Mr Burdis may require plastic surgery
"I was too weak to put out the fire myself so my friend used his hands to put them out. He suffered burns himself.
"There was no reason or motive for what happened, all we did was ask for the time."
Chief Inspector Max Black, of Northumbria Police said: "All we can say at this time is that a flammable liquid was used.
"Tests are still being carried out and until then we are not saying anything further."
Detective are studying CCTV pictures from the area in an effort to trace the youths who carried out the attack.
Apart from ages, the only description of the group of youths who ran off was that they were wearing casual jackets and Rockport shoes.
