Authorities have reported that a 15-year-old boy who was attacked outside a Huddersfield school is in severe condition at the hospital.
At 14:45 BST on Wednesday, emergency personnel were summoned to Woodhouse Hill in response to allegations that a youngster had been attacked and critically injured.
The incident happened near the entrance to North Huddersfield Trust School.
A West Yorkshire Police spokesperson said, “inquiries are underway to establish the circumstances”.
The force said a cordon remained in place as investigations were carried out in the area.

At the cordon which stretches across Woodhouse Hill, people approach police officers and quietly ask for information about the condition of the young man.
The scene is just meters away from the end of the drive which takes you to North Huddersfield Trust School, a secondary with about 900 pupils.
At the time of the attack, the street would have been busy with youngsters near the end of the school day.
There are still groups of young people around, gathered in threes and fours, speaking to each other in hushed tones.
Some residents nearby are out speaking to neighbours, looking at the cordon – everyone is waiting for news.
