Merseyside Police were called to a property on Hart Street in Southport at around 11.50am on Monday, July 29 after reports of a stabbing.

Police declared a “major incident” at the scene in Southport, after receiving emergency calls with armed response vehicles, 13 ambulances, and the fire service descending on the mass casualty scene, a school holiday club for children aged six to 11.

A large police cordon was put up around the building on Hart Road, with police officers guarding either end.

Officers and vehicles could be seen from a distance inside the cordon, including scenes-of-crime officers in white boiler suits.

Merseyside Police Chief Constable Serena Kennedy, giving a statement to media in Southport yesterday evening, said officers were called to a “ferocious” attack.

She said: “When they arrived, they were shocked to find that multiple people, many of whom were children, had been subjected to a ferocious attack and had suffered serious injuries.

“It is understood the children were attending a Taylor Swift event at a dance school when the offender armed with a knife walked into the premises and started to attack the children inside.”

She added the adults who were injured were “bravely trying” to protect the children who were being attacked.

Who are the victims?

Three children died in the attack and eight further were injured. Five of those are in a critical condition.

Two adults are also in a critical condition.

The ages and names of the dead children, or whether boys or girls, have not been given by police, who said they are not treating the incident as terror-related but the motive “remains unclear”.

What do we know about the attacker?

Merseyside Police confirmed that armed police had “detained a male and seized a knife” following the incident.

The force later said a 17-year-old boy from Banks, a Lancashire village to the north of Southport, who was born in Cardiff, was arrested on suspicion of murder and attempted murder.

He will be questioned about the incident, and police said they are working to establish the motive for the attack.

Police confirmed that the incident is not currently being treated as terror-related and said no one else is being sought in connection with it.
