Three members of staff have been arrested following an incident at a city school which left a male pupil with serious injuries.
The staff members at West Gate School for people with special educational needs were arrested and have since been bailed pending further inquiries by Leicestershire Police.
The role of the staff members at West Gate is not known.
A police spokeswoman said the arrests related to "neglect" after a pupil got into difficulty during an activity on January 27.
The council's adult safeguarding team is also believed to be investigating the matter alongside the Health and Safety Executive (HSE).
The pupil was taken to Leicester Royal Infirmary immediately after the incident and has since been transferred to the General Hospital where he remains in a "stable condition" according to the police spokeswoman.
The full nature of his injuries is not known.
Rev Canon Peter Taylor, chair of governors at the school, said: "A number of investigations, including a police inquiry, are being carried out into the circumstances of this tragic incident.
"Three members of staff have been suspended while these take place.
"Staff and parents have been given as much information as the investigations will allow, but until all inquiries are concluded we won't be able to comment further."
West Gate School, in Glenfield Road, moved location across the road into £9.3 million building in October 2014 as part of Leicester City Council's Building Schools for the Future programme.
It looks after pupils aged four to 19 years who have a wide range of learning difficulties and disabilities.
Its last Ofsted inspection took place in 2013 when inspectors from the education watchdog judged it to be "good" overall with some outstanding features.
A message on the school's home page says: "We have a skilled and dedicated staff team who are deeply committed to providing the best possible education and care for all our pupils."
The school is part of a charitable trust alongside The Children's Hospital School, at Leicester Royal Infirmary, and Nether Hall School.
