The 11-year-old girl who was attacked by a blade-wielding elderly lady has 'a long way to go' to recover, according to police sources.
The girl was slashed in the head and hand on Thursday afternoon in Hatton Road, Feltham, by a 70-year-old woman who was sectioned immediately afterwards.
The victim is now recovering at home but will have to undergo hours of therapy after the unprovoked attack.
A Hounslow police spokeswoman said: "The 11-year-old girl has been discharged. She is now receiving physiotherapy and treatment on an outpatient basis. She has a long way to go.
"The 70-year-old woman remains at a West London Hospital pending further inquiries and mental health assessments."
Anyone with information should call Hounslow CID on 020 8247 6160 or Crimestoppers anonymously on 0800 555 111.
