LONDON (AP) — A 30-year-old man was arrested Sunday on suspicion of stabbing six people to death on the British island of Jersey, police said.
Neighbors said the mass killing, inside an apartment in the capital of St. Helier, involved members of the same Polish family.
Police provided no details of the victims or their ages, but said five were declared dead at the scene while a sixth person died while undergoing emergency surgery at Jersey Hospital. The Jersey Evening Post, which didn't cite its sources, said two of the dead are children.
One witness, Andre Thorpe, said he saw police running around the property trying to gain access, then paramedics carrying a bloodied child from the scene.
Jersey's head of crime services Stewart Gull, who is leading the investigation, says detectives haven't established the circumstances of the attack.
"Clearly this complex investigation is in its very early stages as we try to establish exactly what happened," Gull said.
Violent crime is rare on Jersey, a British island dependency about 15 miles (20 kilometers) off the west coast of France's Normandy peninsula.
