Schools on alert over stranger '); '); PARENTS have been warned to beware after two girls making their way to school were followed by a stranger in a car. A Trinity Primary School pupil was stopped by a man driving a white car in Vicarage Road at about 9am on Monday. Police said he made inappropriate comments to the girl and then followed her. At 8.20am today (Thursday) a year 7 pupil at Gillotts School in Henley was approached, again by a white car. The driver, who wore a hat and ski mask, asked if she wanted a lift and the girl fled.
