Police have released a picture of a cyclist left in a coma after he was beaten up in Southampton.
David Baker, 24, was cycling on Central Bridge when he was attacked by a gang on 8 June at 2340 BST.
Police have taken the "unusual" step of naming two people they want to question over the attack Paul Johnson, 21, and Timothy Horstead, 20, of Thornhill.
A 26-year-old man has already been charged with wounding with intent to cause grievous bodily harm.
An 18-year-old woman arrested last week has since been released on bail.
Police have released the picture of Mr Baker in a coma, and another of him before the attack, in the hope it will prompt witnesses or anyone with information to come forward.
Mr Baker suffered head injuries and remains in a critical condition in Southampton General Hospital.
Earlier this week his mother, Jane Hiatt, said the attack had been "devastating for the family".
