The man was seriously injured after Hackney was slashed across the face with a knife.
The man was attacked just after 11 am on July 30 when his moped stopped at a set of traffic lights.
Another man followed behind the victim, who stopped next to him and followed him up Street and Nazrul Street.
Two riders who knew each other dismounted and started quarreling.
The second man then attacked the victim with a knife.
He was taken to the hospital for treatment and later discharged.
The police arrested a 41-year-old man on suspicion of serious bodily harm and threatened to kill. He has since been released on bail.
