A woman has been treated for multiple stab wounds after she was attacked by a seven-year-old boy.
The attack happened in the Norris Green area of the city
The woman, who is in her early 20s, was at a neighbour's home in Norris Green, Liverpool, when they began arguing.
The neighbour's son is believed to have grabbed a kitchen knife and stabbed the woman in the buttock, leg and arm.
The injured woman remains in hospital for treatment for serious but not life-threatening injuries. The boy was not arrested.
The incident happened at about 2015 GMT on Thursday.
A neighbour said she believed the little boy had acted to protect his mother.
She said: "He plays outside a lot and he's had my flowers up before, but he's not a bad lad or a wild child.
"He's a nice little lad but I think last night he's seen the red mist and tried to protect his mum."
A spokeswoman for Merseyside Police said: "It is believed the incident took place during a disturbance between neighbours.
"A child was spoken to but not arrested.
"The investigation is ongoing, and we will be working with other appropriate agencies."
