Greater Manchester Police have released images of a man they want to speak to after a mother was stabbed in front of her young child in a "vicious and unprovoked attack".
Detectives are treating the incident in south Manchester on Saturday afternoon as attempted murder.
The victim, 24, was walking with her five-year-old son on Rudheath Avenue, Withington, when she was approached by a man with a knife.
He began stabbing her before running away along Bromborough Avenue, then continuing in the direction of Whitchurch Road, police have said.
She was taken to hospital where she remains in a stable condition.
Paramedics assessed her son at the scene, but he had no visible injuries.
Police are appealing to the public for help to trace the suspect, and said there would be an increased police presence in the area during the investigation.
