A primary school has closed for a second day after travellers moved on to nearby land.
Litter has been thrown on to the site of Camp Hill Primary in Nuneaton, Warwickshire, the borough council's leader said.
And one of its two pedestrian entrances was "seemingly being used as a toilet", Dennis Harvey said.
The travellers' group, which involved around 20 caravans parked close to the school, has not commented.
The school said closing had been a difficult decision to make but the pupils' welfare was the priority.
Nuneaton and Bedworth Borough Council secured a court order earlier giving the travellers 24 hours' notice to leave before it brought in bailiffs.
The school told parents it was closed indefinitely "due to travellers parking in and around" the school area.
On Facebook, it posted: "We are as angry as you are about the situation but we thank you all for your offers of help and support."
Later, chair of the school governors Heidi Atkins said about half of the travellers "had already left" and she hoped a clean-up would be started on Wednesday on school grounds.
She added Year 6 pupils had been given classroom space by Michael Drayton Junior School on Wednesday as their Sats "are fast approaching".
Katrina Slomczynski, a contributor to the Nuneaton Community Forum on Facebook, said the closure had had a "devastating impact" for parents who could not organise childcare at short notice and needed to take time off work.
The mother-of-two said: "This kind of behaviour gives travellers a bad name, but not every traveller is like this."
County councillor Corinne Davies, a local authority governor at Camp Hill Primary, said: "We visited the site, and there's quite a lot of litter, things like dirty nappies, so we were concerned the pupils wouldn't be completely safe."
