A man has been arrested on suspicion of the murder of a nine-year-old in Liverpool last month.
Olivia Pratt-Korbel was shot in the chest at her home in Dovecot, Liverpool, on August 22.
Her mother, Cheryl Korbel, 46, was also injured as the gunman chased convicted burglar Joseph Nee into their property at about 10pm.
Merseyside Police said on Thursday evening that a 34-year-old man from the area has been taken to a police station where he will be questioned by detectives.
The force added that the investigation into Olivia’s murder remained ongoing and continued to appeal for anyone with information to come forward.
Nine other men have previously been arrested during the investigation, but have all been released on bail.
The reward offered in the hunt for the killer had been increased to £200,000.
Police also revealed earlier in the investigation that the two weapons used were a .38 revolver – the gun responsible for killing Olivia – and a Glock-type self-loading 9mm pistol which was fired in the initial stages of the incident.
Earlier this month her funeral was held at St Margaret Mary’s Church in Knotty Ash.
