Officers are continuing to search a house in Stourport Road in Kidderminster after suspicious items were discovered there on Saturday (29 June).
A cordon has been in place at the address since Saturday following the discovery of substances that it is suspected could be used in the production of explosives.
In partnership with experts from Explosive Ordnance Disposal (EOD), officers have been carrying out painstaking and methodical searches throughout the weekend.
EOD finished their searches last night and the 100m cordon that was in place for much of the weekend was removed at around 10pm, meaning all residents could return home.
Officers remain on scene today conducting further searches of the property.
A 51-year-old man was arrested on Saturday afternoon in connection with several offences, including explosives offences, and remains in police custody.
Officers initially attended the property on Saturday afternoon following a report of dangerous dogs, and once inside discovered the suspicious items.
Superintendent Melanie Paley, local policing lead for north Worcestershire, said: “I’d like to thank the local community for their patience over the weekend and into today as our searches continue. I don’t underestimate how unsettling and inconvenient it was for you to be out of your home for most of the weekend.
“The safety of the public is absolutely paramount and it was important that these specialist searches were carried out meticulously and they could not be rushed.
“I know the news that items linked to suspected explosive substances being found in this residential area will be alarming. We’re keeping an open mind on how and why the substances came to be there and a thorough investigation is already underway.
“I would ask people not to jump to conclusions about the incident as speculation and rumour will hamper and slow down our investigation.
“Officers will continue to be in the area in the coming days and I’d urge anyone with any concerns to have a chat with them.”
Ian Miller, Chief Executive of Wyre Forest District Council, said: “The council set up a rest centre at our headquarters Wyre Forest House on Saturday night. This was available to anyone who could not make their own arrangements for somewhere to stay.
“Three individuals used the facility and a family attended but did not stay. On Sunday we arranged for three individuals and two families (as well as their dogs) to spend the night in hotels in or near Kidderminster.
It must have been a very difficult time for those living in the area and we thank them for their patience and understanding. My thanks also to everyone who assisted with this emergency response.“
