Workers, bus passengers and schoolchildren have all been affected by a major explosion which happened at an industrial estate last night.

Police, fire and ambulance crews were called to the Rackheath Industrial Estate after reports of a suspected gas explosion at about 9.15pm at the KC Cafe.

The blast is believed to have been felt in and around several of the surrounding villages and initial reports from fire crews on the scene - who set up a cordon - indicated that debris from the blast was been spread over an area of some 8,000 square metres.

Residents in Little Plumstead, Blofield Heath and Postwick reported a boom while houses in Salhouse were shaken by the explosion.

The site will now be closed for the foreseeable future while checks are carried out on the building.

People who work on the estate have been told not to go into work this morning and Anglia Bus has had to cancel a number of its services this morning.

The bus company's depot for Norwich services is based at the site and cannot access its vehicles until a safety assessment is carried out today.

Services affected are the A47, 121, 122, 123, 124, 125, 830, 999 and L2.

Bus company bosses are expecting a police update at midday.

An Anglia Bus spokesman said: 'We can't get the drivers to work so we can't get the vehicles out on the roads and local workers to work and schoolchildren to school.

'We are sorry for any inconvenience caused but this is due to circumstances out of our control.'
