Norfolk Police say they've had a call to say a man's found what he thinks is an artillery shell on the beach about a quarter of a mile from Bacton, towards Mundesley.
Explosive Ordnance Disposal have been called and the police have set up a cordon.
A major emergency exercise will take place today at a gas terminal on the Norfolk coast.
The Bacton complex receives natural gas from the southern North Sea. It also has pipeline connections to Europe and the UK.
People living near the site are being told not to be alarmed if they hear sirens and see emergency vehicles arriving at the terminal.
A Norfolk village cricket club has been asked to leave its ground after a disagreement with its Parish Council.
The Bacton club has been in the village for 79 years, but the Parish Council says it's repeatedly failed to comply with regulations.
Development Manager for the Norfolk Cricket Board, Keiron Tuck, says they are working with the Bacton club to find other venues for the rest of the season.
Bacton Parish Council in Norfolk says it has been misrepresented after the village cricket club said it had been evicted in a row over practising with a hard cricket ball.
In a statement on its website the council says it has not banned fielding and wicket keeping practice.
The statement continues: "The problems with the cricket club are of a completely different nature and have little to do with health and safety but everything to do with the failure of the club to co-operate with the parish council over a number of matters."
A cricket club at the centre of a row over whether or not players can practise with hard balls claims it's been evicted.
A headline on Bacton Cricket Club's website says:
Bacton Cricket Club in Norfolk says it’s been banned from its home ground after refusing to stop using hard balls when practising on the pitch.
The parish council says new rules are being enforced to protect people after some near misses on the public field.
Now the club is set to relocate to North Walsham after 37 years at the Cubitt Memorial Playing Field.
