An ambulance trust has come under fire for using sirens and 'disturbing the peace' of a village in Suffolk. East Anglian Ambulance trust was criticised last month for 'overstating' response times in an independent inquiry. Now parish councillors in Cavendish, near Sudbury, have written to the trust protesting that sirens are being used too often. A trust spokesman said complaints about ambulances making too much noise were 'rare' and crews only used sirens 'when they feel it may be unsafe not to do so'.
