Merseyside Police have appealed for anyone who saw the black Audi Q3 in the days before the shooting to come forward. The car was impounded and is in the process of a forensic examination. The schoolgirl was shot on Monday night by a gunman who chased his target into the family’s home in Dovecot, Liverpool, also injuring her mother Cheryl, 46. Merseyside Police said a 36-year-old man, from the Highton area, was arrested on suspicion of Olivia’s murder and two counts of attempted murder following an operation with armed officers on Thursday night. He is currently in custody and being questioned by detectives. The Audi has been impounded and is undergoing a forensic examination (Merseyside Police) Detective Superintendent Mark Baker said: “Although we have made an arrest in connection with Olivia’s horrific murder, I want to make it absolutely clear that we need any information about this vehicle or the wider investigation more than ever. “Whatever information you have, and whether you’re sure it’s the same vehicle or not, please pass it on and we’ll assess its significance.” Olivia’s family have paid tribute to her, describing her as a “unique, chatty, boisterous little girl who broke the mold at birth”. They added: “Although her life was short, her personality certainly wasn’t and she lived it as long as she could and would lift people up with her spirit and kindness.” The family urged people to ‘do the right thing’ and said: ‘If anyone knows anything, now is the time to speak up. It’s not about being ‘leveraged’ or ‘grass’, it’s about finding out who took our baby.’ Additional report from PA
