A murder investigation has been launched after a nine-year-old girl was fatally shot in Liverpool.

Merseyside Police officers attended a house on Kingsheath Avenue, Knotty Ash, at 10pm on Monday following reports an unknown male had fired a gun inside the property, according to a statement from the force.

The nine-year-old girl suffered a gunshot injury to the chest and was taken in a critical condition to hospital, where she later died.

A man also suffered gunshot wounds to his body and a woman suffered a gunshot injury to her hand during the incident inside the house, the force added.

They have both been taken to hospital for treatment for their injuries.

Assistant Chief Constable Jenny Sims said: “This is a truly shocking incident in which tragically a young and innocent girl has been shot and sadly died.

“Our thoughts and condolences go to her family and friends at this very difficult time. No parent should ever have to suffer the loss of a child in these dreadful circumstances.

“This crime is abhorrent and our communities must come forward and tell us who is responsible.

“This cowardly individual does not deserve to be walking the streets and I would urge those who know anything to speak to us and tell us what they know so that we can put the person responsible behind bars where they belong.

“We are carrying out a number of lines of enquiry as a matter of urgency and would ask for dashcam, CCTV or mobile phone footage from anyone who lives, works or was visiting the area of Kingsheath Avenue last night.”
