The card said how much they loved the 12-year-old, how they were going to miss Ava and their shock at what has happened.

More flower tributes have been paid by people visiting the city centre since the news of Ava's death broke on Friday morning.

A North Face hoodie was also wrapped around a tree alongside the flower tributes.

Today, the family of Ava released two new photographs which show the young girl in her uniform and smiling while seemingly out at a restaurant.

It comes as Merseyside Police issued an image of a van - officers would like to speak to the occupants who may have witnessed the assault on Ava.

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

When officers arrived they discovered Ava, who was out with friends following the Christmas switch-on, collapsed on the ground while a member of the public who witnessed the attack was giving first aid.

Paramedics attended at the scene and Ava was taken to Alder Hey Children’s Hospital where sadly she died a short time later despite the best efforts of medical staff.

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

Road closures remain in place on School Lane, Church Alley and Fleet Street as our extensive enquiries continue.
