A teenage boy is due to appear in court on Monday after he was charged with the murder of a 12-year-old girl in Liverpool city centre.
Ava White had been in the city with friends on Thursday following a Christmas lights switch-on when she suffered “catastrophic injuries” in an assault at 8.39pm, Merseyside Police said.
The 14-year-old boy, who cannot be named for legal reasons, has been charged with murder and possession of a bladed article.
Three other boys, aged between 13 and 15, were also arrested and have been conditionally bailed as inquiries continue.
Ava, who has been described as “popular” and “bright”, was involved in a “verbal argument” which escalated into an “assault on her with a knife”, police said.
The force said the offenders ran off up School Lane, across Hanover Street and into Fleet Street after the incident took place.
Ava was taken to Alder Hey Children’s Hospital after paramedics arrived but died a short time later.
On Friday, flowers were laid on Church Street in tribute to the Notre Dame Catholic College pupil, as forensics officers and police searched the scene.
A balloon was left by 17-year-old Lacey, who did not want to give her surname, who said her younger sister had been close friends with Ava.
She said: “She was just a bubbly character, so loving and caring.
“She came out with her friends to enjoy herself and I think it’s just wrong that this has happened.”
Headteacher Peter Duffy said: “She was an incredibly popular girl with a fantastic group of friends.”
Assistant Chief Constable Ngaire Waine said the incident was “sad for the city” but “even sadder” for Ava’s family.
On Saturday, police issued an image of a van which may have been occupied by key witnesses to the incident.
Detective Superintendent Sue Coombs said: “We’re continuing to support Ava’s family and they have requested that their privacy continues to be respected at this difficult time.
“It’s also vitally important as we continue the investigation that nobody posts comments or names on social media which could potentially impact upon us getting justice for Ava’s family.
“Please trust us that we are doing all we can to investigate and update people on this tragic incident, and we do not want anything to jeopardise this.”
Ms Coombs urged anyone who captured the incident or aftermath to send images or footage to the force online at: https://mipp.police.uk/operation/05MP21M43-PO1.
