Work on the unexploded bomb in Great Yarmouth has come to a halt after the sand wall was compromised.

The Second World War bomb was reported to police on Tuesday after it was dredged out of the River Yare.

Water has reduced the integrity of the sand barrier built around the bomb and work is needed to repair it which may take a number of hours.

Once this is done, army specialists will continue cutting into the bomb.

Norfolk Constabulary's assistant chief constable Nick Davison said: "We understand this has been an incredibly slow process but it’s needed to be for the safety of the public and those involved in disarming the device. 

"We’re hopeful a significant part of the operation will be finished today and we will keep the public updated."

A 400-metre cordon remains in place with a strict 200-metre inner cordon that people are banned from entering.

A no-fly zone in the immediate vicinity of the device was put in place on Wednesday and will remain until further notice.

Great Yarmouth Borough Council chief executive Sheila Oxtoby said: "We are acutely aware how disruptive this has been.
