The main advertising banner for the Chinnor flower show has gone missing and organisers are unsure if it was a prank or an act of sabotage.

John Robertson, a member of the organising committee said: "We needed the banner to show that this year's event will be on the playing fields, not in the village hall.

"It was put up on the playing field fence - and now it has gone.

"We're not sure whether it was sabotage or a stupid prank, but the police have been informed."

The annual show will be on Bank Holiday Monday on the playing fields.
