A £12,000-a-year private school has closed its doors to pupils after travellers settled on its grounds overnight.
Staff at the Lancashire-based AKS Lytham turned students away this morning, claiming it was "unsafe" for them to attend school.
There were reports of around six caravans parked on the school's fields, as well as dogs running loose.
"We are having to tell parents that school isn't on today," the school's receptionist said.
"There are dogs running around and it is felt it isn't safe for the pupils to be in."
A Facebook post believed to be written by one of the travellers, named Susan Scott, said they had intended to stay on the school's grounds for "eight weeks".
"We have every right to be on there as there was no gate or sign to say we couldn't go on," the post read.
"My caravan is clean and we don't leave mess."
However, the group of travellers agreed to leave the site under police escort this afternoon.
In a statement posted to on the school's Twitter page, parents were assured the situation had "now been resolved" and that AKS Lytham would be "open as usual" tomorrow.
Parent Lucy Victoria, said the school had made the "correct decision" to close.
"Keeping the children safe is of paramount importance," she added.
AKS Lytham has more than 500 pupils aged from three to 18.
