The warning was made by deputy head of Simon Langton Girls’ Grammar School Rob Green after the incident in St George’s Street, Canterbury.

Police officers investigating confirmed they arrested a 21-year-old, who has since been released on bail until February 19.

In a letter to parents, Mr Green said there had been a “safeguarding incident” involving pupils at the school.

“I would like to assure you that the police are investigating this incident and working with both parents and students,” he said.

“We would like to remind all parents and students once again to be mindful of personal safety travelling to and from school and at all times.”

Police spokesman Scarlet Jones confirmed there had been a report of a pupil from the school being followed in St George’s Street by a man acting suspiciously.
