Police searched three properties in Great Yarmouth, Gorleston and Burgh Castle in connection with an armed robbery in Suffolk.
Armed police were involved in raids at addresses in Norfolk as part of an investigation into an armed robbery in Suffolk.
Police swooped on three properties in the Great Yarmouth area with armed units, the dog section, plain clothes officers and the police helicopter all involved in last night's operation.
Warrants were executed at addresses in Prince's Road, Yarmouth; Baliol Road, Gorleston; and the Waveney Valley Holiday Park, in Burgh Castle in a trio of raids last night.
In Prince's Road, there were six police vehicles and a police helicopter was also seen hovering ahead.
The road was closed and police moved people away from the scene, although large crowds gathered.
The operation was over within an hour, although one car remained at the scene.
A force spokesman said investigations were 'ongoing' but would not give any more details about how many people were arrested or whether the operation was linked to the armed robbery at Beccles earlier this month.
As previously reported, four armed men were involved in a robbery at Copperfield Jewellers, in New Market, at around 4pm on September 16.
It is believed that the robbers had a shotgun and a knife and all four had their faces covered.
Nobody was injured during the incident.
Speaking last week, a police spokesman said: 'It is reported that four men entered the business and threatened the owner before stealing a number of items. It is understood that the suspects then fled the scene on foot in the direction of Ballygate.'
