A four-year-old boy has been stabbed to death in West Yorkshire.
Police are now conducting an investigation at the scene
A 14-year-old girl was also seriously injured in the incident in Royd Street, Slaithwaite, on Sunday afternoon.
The teenage girl has been taken to Huddersfield Royal Infirmary with stab wounds. Her condition is described as serious.
West Yorkshire Police are treating the death as murder. Two men, one aged 47, have been arrested in connection with the incident.
BBC correspondent Danny Savage said the girl had eventually fallen in the street after being attacked, and that specific area was being examined.
The owner of a corner shop at the end of Royd Street said he had tried to help the girl.
Waqar Zaman, 34, said he found the girl lying in the street and removed his T-shirt to try to stem the flow of blood.
"She had a stab wound on her face which went straight through her mouth, she had stab wounds in her stomach just under her rib cage, all over the place," he said.
"She was complaining she couldn't breathe, that she was going to die."
Local residents expressed their disbelief over the incident.
Neighbour Paul O'Shea said: "We are very shocked. It happened right across the road from us.
"Seven or eight houses have been blocked off and the residents are not being allowed out.
"The first we heard about anything was when the police arrived. It's a terrible thing to happen."
