Up to 1,000 homes in Plymouth could be evacuated after the discovery of an unexploded bomb.
About 1,000 residents evacuated from their homes in a Devon city after a 500lb (227kg) bomb was found, have returned to their homes.
The device was found by workers on a building site in Brentor Road, in the Prince Rock area of the city.
They were in the 100m (328ft) radius of a building site in Prince Rock, Plymouth where workers uncovered the bomb at 1800 BST on Tuesday.
It is sticking about six inches (15cm) out of the ground and is 10ins (25cm) in diameter.
They returned to their homes at 0100 BST the following day.
Bomb disposal experts have confirmed it weighs about 250lb (113kg). It is thought the device will be removed from the site and detonated at sea.
Bomb disposal teams took the device out to sea where they will carry out a controlled explosion on Wednesday.
A police spokesman said it was likely to be a World War II device. Plymouth was targeted by German raids during the war because of its importance as a major naval port.
'Everybody helpful'
Specialist equipment has been sent to Plymouth from Wales and when the bomb is moved, buildings on the route may also have to be evacuated.
There were scenes of confusion in Prince Rock on Tuesday night as residents returning home from work found they could not go anywhere near their homes.
"Evacuations are being carried out of properties within 100m [328ft] of the scene," a police spokesman said.
Some of the evacuees took refuge in the Friary Vaults members bar, where proprietor Sue Aston said: "We are right on the edge of the evacuation area, and a lot of the people are our members anyway.
"Properties within the 100m-300m [328-984ft] zone are being advised to open windows and draw curtains."
"But tonight we are letting in people whether they are members or not."
Some people unable to get into their homes when they returned from work have said they are worried about their pets.
One elderly woman said: "I went through the Blitz and this reminds me of the war.
Bomb examined
"Everybody has been very helpful and friendly."
Plymouth City Council's emergency planning officer is at the scene and the council has taken residents with no alternative accommodation to Stoke Damerel Community College.
Plymouth was targeted by German raids because of its importance as a major naval port.
The Explosive Ordnance Disposal (EOD) team will not begin to examine the bomb until the 100m zone has been fully cleared.
The dockyard area around Devonport, as well as the city centre, were badly hit by bombing.
The operation is expected to last for several hours.
Extra police units from Devon and Cornwall were called in to help with the evacuation, and nearby Tothill Park has also been closed to the public.
Some of the residents took refuge in the Friary Vaults members bar, on the edge of the evacuation area.
Proprietor Sue Aston said: "A lot of the people are our members anyway, but tonight we are letting in people whether they are members or not.
"They are bit shocked at the moment at not being able to get home."
