A Sheffield primary school has been forced to shut after a staff member was arrested over allegations of sexual abuse.
Parents of children at the school have withdrawn their children from Greenlands Nursery Infant School in Darnall to express their anger at the lack of information they have been given.
The staff member, who is believed not to be a teacher, has been questioned by police after a young boy made claims of a "serious" sexual assault on Friday. The boy told his mother about the alleged incident, who then notified the school.
Many parents have stopped their children from attending classes on Monday and Tuesday until more information is supplied by the school - which has around 350 pupils between three and seven.
Police claim the alleged sexual assault is an "isolated" case but would not confirm the suspect's gender.
Head teacher Sue Daniels confirmed a member of staff has been questioned and has been suspended until the claims have been investigation.
Council officials and police held a meeting at the school on Monday evening which was attended by around 250 parents - some of whom had to wait outside as the hall was full.
Sheffield City Council's director of children and young people's services Dr Sonia Sharp called the incident "incredibly distressing" for both parents and staff at the school.
A statement by South Yorkshire Police said a person was arrested in connect with the matter and has been released on police bail pending further enquiries.
"The Darnall and Tinsley Safer Neighbourhood Team are working with the local community to address any concerns and the investigating officers currently believe the alleged incident to be isolated."
