A former Merseyside Police officer has issued a "vital plea" on Good Morning Britain.
John Williams appeared on today's edition of the ITV news programme as police remain on the hunt for the gunman responsible for Olivia Pratt-Korbel's murder. Mr Williams was a Detective Chief Inspector and spent 30 years investigating gangs in Liverpool.
He urged anyone with information to come forward so the person responsible for the killing of the innocent nine-year-old can be brought to justice. Mr Williams said: "I will implore the community out there to speak to the police and try to prevent this from ever happening again."
