Elliott John Stables, 28, of Finsbury Street, has been charged with one count of robbery following an alleged incident on Durham Road at 8.30pm on Thursday, July 7.
Northumbria Police said officers were called after it was reported that a 27-year-old man was approached by three other men and for reasons yet to be established, one of the men then struck the victim on the back of his head with a heavy object before taking his mobile phone and wallet.
Police say the victim was knocked unconscious and was later taken to hospital with serious head injuries, where he remains in a stable condition.

I am asking those people who were in the area to get in touch.“If you think you may know any information that can assist our investigation, or perhaps have any footage such as CCTV or dashcam that could prove useful, then we want to hear from you.”
