A man has been arrested after handing himself in to police following the stabbing of a mother in front of her child in Streatham, south London.
The 43-year-old, who has not been named, was arrested on suspicion of attempted murder and suspected possession of offensive weapons. He visited a west London police station in the early hours of Thursday morning, the Metropolitan police said.
The victim, 36, was approached from behind by a lone attacker while pushing her child in a pram on Downton Avenue, Streatham Hill, shortly before 5.30pm on Monday. She was stabbed three times before the assailant fled.
She was taken to hospital with injuries that were not life-threatening or life-changing. Her child, whose age has not been released, was not hurt.
The attacker did not speak to the victim during the incident, and the two are not thought to have known each other. The suspect remains in police custody as inquiries continue.
