A man wearing a clown mask is driving around in a white van and asking schoolchildren if they want a lift, it has been claimed.
Parents have been alerted about "individuals wearing clown-like masks" with a child left "upset and frightened" when they were approached as they made their way to school.
Garrett Murray, the headteacher of St John Fisher Catholic College in Newcastle, has sent a letter warning parents about a "suspicious white van" in the area, reports StokeonTrentLive.
He wrote: "We have been informed by the police that a number of reports have been received by them regarding a suspicious white van stopping a number of young people in the Wolstanton and wider area.
"In one report, a young person was asked if they wanted a ride and another report suggests that individuals in the van were wearing clown-like masks which upset and frightened a young person on their way to school.
"Local police will patrol around the location throughout the day. I am asking learners, parents and carers to be vigilant and to report any concerns to Staffordshire Police on 101 or via the Staffordshire Police website or Facebook page. Any descriptions or identifying markers such as vehicle registration plates would be extremely useful in helping the police with their enquiries."
Any sightings of the van over the Easter holidays should be reported to the police on 101 or via the social media channels.
St John Fisher Catholic College has more than 1,000 pupils aged 11 to 18 registered at the academy secondary school. It was rated good by Ofsted inspectors at its last inspection in 2016.
