A picture has been released of a Kurdish man - who was set upon by a mob of around 20 people in a suspected hate attack - recovering in hospital.
Reker Ahmed, 17, is seen sitting up in bed, with what appears to be two black eyes, flanked by Kurdish community leaders.
Mr Ahmed was placed in an induced coma after the alleged hate crime left him unconscious, with a fractured skull and spine and a blood clot on the brain.
He and two friends were waiting at a bus stop in Shrublands Avenue, near The Goat pub in Croydon, south London, at about 11.40pm on Friday.
Police say Mr Ahmed, a Kurdish-Iranian, was chased and subjected to a "brutal attack" including "repeated blows to the head".
His friends managed to escape with minor injuries.
Thirteen people have been charged with a variety of crimes, including violent disorder and racially aggravated grievous bodily harm, in connection with the attack.
A crowd-funding site set up for Mr Ahmed has raised more than £44,000.
Theresa May has condemned the "absolutely despicable" attack and said she hoped people with information would contact police.
