A woman has been arrested after a seven-year-old girl was stabbed to death in a "totally unprovoked and random attack" in a park in Greater Manchester.
The child "sustained horrendous injuries", police said.
Despite the efforts of her family and paramedics, she died a short time later in Queen's Park in Bolton on Sunday afternoon.
The 30-year-old woman, who has "some history of mental illness", is not known to the girl's family.
She was detained at the scene by a member of the public, and arrested initially on suspicion of attempted murder and subsequently for murder.
Assistant Chief Constable Russ Jackson from the Greater Manchester force said "words cannot describe how awful this attack is".
He added: "The family were out in the park, enjoying the spring sun when in a totally unprovoked and random attack this little girl sustained horrendous injuries and sadly died a short while later.
