Merseyside Police said the 37-year-old, from West Derby, was arrested on suspicion of assisting an offender and remains in custody being questioned by detectives. In a statement, the force added: “The investigation into Olivia’s murder is ongoing and we continue to appeal for anyone with information to come forward to help us bring those responsible to justice.” It comes after two arrests were made in West Derby on Thursday in connection with the killing when police executed warrants at three properties. Nine-year-old Olivia was shot at her home last month when a gunman chased a man into a house in the Dovecot area of ​​Liverpool at around 10pm. Earlier this week, Olivia’s mother, Cheryl Korbel, who was also injured in the shooting, appealed for the killer to surrender. A service is to be held for Olivia in Liverpool on September 15. Detectives said people with a CCTV, dash cam or smart doorbell can upload them to a special portal for the investigative team.
