A schoolboy was approached by a stranger who demanded he get into his car. 

The driver of a black BMW tried to stop the boy on a road close to Ryvers School.

The incident came to light after the secondary school student told his parent what had happened and it was reported to police on January 20.

Ryvers School confirmed it was not one of their pupils involved but wrote to parents to alert them and asked them to remain vigilant as a precaution.

In an email to parents, Ryvers School said: "Whilst we do not want to alarm you, we ask that you are vigilant and remind your children about the importance of not talking to strangers."

Executive Headteacher Pete Rowe added: "There was no suggestion that the incident involved any younger children or those at Ryvers.

"That said, having been alerted to the incident and it being in the local community, we felt it sensible to put out the alert and ask parents to be particularly vigilant.

"I stand on the school gate morning and afternoon with my trusty therapy dog and have had no feedback from anyone post the incident."

Thames Valley Police was contacted but were unable to provide more details.
