A 400m cordon remains in place in Great Yarmouth after an unexploded bomb was discovered. 

The unexploded bomb which is thought to be from the Second World War was found by workers at the construction site of the third river crossing in Southown Road at about 11.35am on Tuesday. 

The device was found during dredging work in the River Yare at Bollard Quay, close to the junction with Boundary Road.

A number of nearby roads have been closed while army specialists deal with the unexploded device. 

A rest centre was set up on Tuesday night in order to provide refuge to the evacuated locals.

People who are asked to evacuate are strongly advised to do so and those who are unable to seek refuge with friends and family can go to one of the two rest centres.

A no-fly zone has also been put in place in Great Yarmouth as the army begins cutting into the unexploded bomb. 

The cordons are set to remain in place until at least 11am today (February 9) but people are being warned that this might change. 

Superintendent Nathan Clark of Norfolk Constabulary said: “This is a very delicate, complicated, and dynamic situation and we do not underestimate the impact this is having on people’s lives.

“This operation is now moving into the next phase. The police together will our partner agencies and the bomb disposal experts continue to work together to try to get this resolved as safely and as quickly as possible.”

The public is asked to stay away from the area to let the specialists work.

An emergency helpline for people who require assistance with evacuation from the exclusion zone is also still available. This helpline is 01493 330369 and should not be used for general advice.
