One of Abingdon's leading independent schools has apologised to its neighbours after staging a noisy fireworks display as part of its centenary celebrations.

St Helen and St Katharine School, in Faringdon Road, held a gala concert and rounded off the evening with a 20-minute fireworks display in the grounds.

The school said it received four complaints after the display, at about 10.30pm on Sunday, about half-an-hour later than intended.

Headteacher Cynthia Hall said: "We wrote to neighbours telling them that there would be a fireworks display after the concert.

"Unfortunately, there was one loud bang that had not been planned.

"We apologise to anyone who may have been disturbed."
