A nine-year old girl wounded in a stabbing attack at a Taylor Swift-themed dance and yoga class in northwestern England died Tuesday, bringing the death toll to three, as police questioned a 17-year-old suspect arrested minutes after the rampage.

Merseyside Police said the other fatalities were girls aged six and seven.

Eight children and two adults remain hospitalized after Monday’s attack in Southport, during a Swift-themed yoga and dance workshop for children aged about six to 11. Both adults and five of the children remain in critical condition.

Swift said she was “completely in shock” and still taking in “the horror” of the event.

“These were just little kids at a dance class,” she wrote on Instagram. “I am at a complete loss for how to ever convey my sympathies to these families.”

Teenage boy arrested

Police have named the dead as Bebe King, 6, Elsie Dot Stancombe, 7, and Alice Dasilva Aguiar, 9.

Local people left flowers and stuffed animals in tribute at a police cordon on the street lined with brick houses in the seaside resort near Liverpool — nicknamed “sunny Southport” — whose beach and pier attract vacationers from across northwest England.

Witnesses described scenes “from a horror movie” as bloodied children ran from the attack just before noon on Monday.

The suspect was arrested soon after on suspicion of murder and attempted murder. Police said he was born in Cardiff, Wales, and had lived for years in a village about five kilometres from Southport. He has not yet been charged.

Police said detectives are not treating the attack as terror-related and they are not looking for any other suspects.

“We believe the adults who were injured were bravely trying to protect the children who were being attacked,” Merseyside Police Chief Const. Serena Kennedy said.

It is the latest shocking attack in a country where a recent rise in knife crime has stoked anxieties and led to calls for the government to do more to clamp down on bladed weapons, which are by far the most commonly used instruments in U.K. homicides.

Witnesses described hearing screams and seeing children covered in blood emerging from the Hart Space, a community centre that hosts everything from pregnancy workshops and meditation sessions to women’s boot camps.

Royals send condolences

“They were in the road, running from the nursery,” said Bare Varathan, who owns a shop nearby. “They had been stabbed, here, here, here, everywhere,” he said, indicating the neck, back and chest.

Prime Minister Keir Starmer called the attack “horrendous and deeply shocking.” King Charles sent his “condolences, prayers and deepest sympathies” to those affected by the “utterly horrific incident.”

Prince William and his wife, Catherine, said that “as parents, we cannot begin to imagine what the families, friends and loved ones of those killed and injured in Southport today are going through.”

Colin Parry, who owns a nearby auto body shop, told The Guardian that the suspect arrived by taxi.

“He came down our driveway in a taxi and didn’t pay for the taxi, so I confronted him at that point,” Parry was quoted as saying. “He was quite aggressive, he said, ‘What are you gonna do about it?”‘

Knives used in about 40% of homicides

Parry said most of the victims appeared to be young girls.

“The mothers are coming here now and screaming,” Parry said. “It is like a scene from a horror movie … It’s like something from America, not like sunny Southport.”

Britain’s worst attack on children occurred in 1996, when 43-year-old Thomas Hamilton shot 16 kindergartners and their teacher dead in a school gymnasium in Dunblane, Scotland. The U.K. subsequently banned the private ownership of almost all handguns.

Mass shootings and killings with firearms are rare in Britain, where knives were used in about 40 per cent of homicides in the year to March 2023.

Although mass stabbings are also rare, several in recent years have generated fear and outrage and received a tremendous amount of attention:

• In London in April, a man with a sword killed a 14-year-old boy walking to school and seriously injured four other people, including two police officers.
• In Nottingham in central England in June 2022, a paranoid schizophrenic man fatally stabbed two college students walking home from celebrating the end of the school year and then killed a 65-year-old man, stole his van and used it to hit three pedestrians.
• In Reading, west of London, in June 2020, a failed Libyan asylum seeker fatally stabbed three men and wounded three others.
