The family of Ava White have released new pictures of the 12-year-old as the murder probe continues.

At around 8.39pm on Thursday night, 25 November, officers were called to reports of an assault in the area of Church Alley.

When they arrived, they discovered that Ava, who had been with friends collapsed on the ground with a member of the public who witnessed the incident giving her first aid.

Paramedics attended at the scene and Ava was taken to Alder Hey Children’s Hospital, where she died a short time later.

Four teenage boys – one aged 13, two aged 14 and one aged 15 years, all from the Dingle area remain in custody for questioning.

“To be clear, we think those vehicle's occupants are witnesses, and in no way suspected of being involved.

“However, we still need to speak to those people as soon as possible to confirm what information they might hold. 
“We’d also urge anyone else who has captured the incident or aftermath to send any images/footage directly via the following link: 

“Four males remain in custody for questioning, and a part of the city centre remains cordoned off while we continue our work.

“I’d like to thank the businesses and residents in the area for their patience and understanding while we make these vital enquiries.
“I’d also like to take this opportunity to remind people not to make any comments on social media which might potentially jeopardise our investigation, including of course names of any people potentially involved.

“We welcome any such information, but please only pass it on in the following ways so we can continue to make progress in our investigation.”
