Organisers of Saturday's Swaffham fun day say a small minority who vandalised the venue the previous night will not deter them from holding the event again next year.

The vandals shredded a large plastic banner donated by local sign makers IRS to promote the annual event, which highlights activities for young people in the town, and pushed concrete caps off the Nelson centenary gates at the entrance to the recreation ground.

Sheila Lister, who helped organise the event, said: 'Not in God's earth will this stop it. The more they do it the more determined I am to bring them to justice and make sure other kids can enjoy [the recreation ground].'

The fun day on Saturday June 16 saw young people from the town demonstrate their skateboarding, rugby, martial art and musical skills.

Town clerk Richard Bishop said: 'It is petty vandalism of this type that stops improvements being made to the town as the cost is not sufficient to warrant an insurance claim but it takes away money from budgets allocated for other things.

'It is gross stupidity and every single council tax payer contributes towards putting right vandalism of this type. Townsfolk are urged to report any acts of vandalism to the police or to the Town Hall. Any information that leads to the arrest of those concerned would be appreciated.'
