The man is suspected of assisting an offender and has been taken into custody to be questioned by detectives. It comes after police on Thursday executed warrants at three properties in the West Derby area of ​​Liverpool. Property searches are ongoing. Olivia was shot dead by a gunman who forced his way into her family home in the Dovecot area of ​​Liverpool at around 10pm on August 22. The gunman was after a convicted burglar, Joseph Nee, who had broken into the house when Olivia’s mother, Cheryl Korbel, opened her front door to see what the commotion was going on outside. Police have renewed their appeal for anyone with information. People who may have a CCTV, dash cam or smart doorbell can upload it to a special portal where they will be taken straight to the investigation team, detectives said. Korbel and Olivia’s father, John Francis Pratt, posted separate messages asking for more information. “You know you’ve made a mistake, so you have to own up to it, like I taught my kids. You’re doing something wrong, you realize it,” Korbel said in a video statement. “If someone is hiding these weapons they need to speak up because they need to be off these streets. No one, no one should have to go through this.” Four men arrested on Sunday, including one suspected of killing Olivia, were released on conditional bail on Wednesday. Police praised the public’s response as “phenomenal” but said more was needed. Assistant Chief Constable Chris Green said: “This is a detailed, complex investigation. Those who were responsible don’t come forward and say, “Right, I was responsible…there you go.” We have to go and uncover all the evidence.” Olivia’s funeral is due to take place at St Margaret Mary’s, the church associated with her school, in Dovecot on September 15. The family asked mourners to “wear the color pink”.
