Police and a bomb disposal unit were seen at a property in Pitstone yesterday morning (Wednesday).
Officers carried out a search at an address on Morton Close at around 8am.
The pre-planned warrant was to establish whether any criminal offences were taking within the property and officers remained at the address to conduct enquiries.
As part of the search, officers are being supported by specialist teams, including EOD (Explosive Ordnance Disposal) as a precautionary measure to maintain public and officer safety.
A police spokesman said: "There is no immediate cause for the public to be concerned and the local community are thanked for their support and understanding."
No one has been arrested.
