On Tuesday, 30 July, Met Counter Terrorism officers obtained a warrant of further detention for a 59-year-old man arrested in Suffolk.
The warrant was authorised by Westminster Magistrates’ Court on Tuesday, 30 July and lasts until 12:12hrs, Sunday, 4 August.
On Sunday, 28 July, officers from Suffolk Constabulary carried out a pre-planned operation at a property on Normanshurst Close in Lowestoft, Suffolk. Officers searched the address and recovered two military grenades and a firearm.
Officers arrested a 59-year-old man from Suffolk on suspicion of possession of a firearm at approximately 12:10hrs that day.
The grenades were assessed and found to be inert. It is believed that the firearm is an imitation firearm.
Met Counter Terrorism officers were called to assist as a quantity of chemicals were also recovered. Subsequently, the man was further arrested on suspicion of being concerned in the commission, preparation and instigation of acts of terrorism. He has been detained under Section 41 of the Terrorism Act, 2000 and is currently in custody at a Suffolk police station.
As a precautionary measure, police cordoned off the area surrounding the address and evacuated three neighbouring properties.
A 100-metre cordon was lifted on Monday evening while a much smaller cordon remains on the property and the neighbouring properties remain evacuated.
Detective Chief Superintendent Alexis Boon, of the Met’s Counter Terrorism Command, said: “After a pre-planned operation by Suffolk Constabulary in which officers arrested a man, the Met’s Counter Terrorism Command is now leading this investigation, working closely with police in Suffolk.
“Suffolk Constabulary acted quickly to make the area safe, including erecting a cordon around the address as a precautionary measure while enquiries are ongoing, however we have found nothing to suggest an ongoing threat to the public.
“I would like to thank the community for its understanding and patience while officers continue this work.
“Local officers from Suffolk Constabulary Safer Neighbourhood Teams will remain at the scene over the coming days to continue to provide reassurance.”
Enquiries are ongoing.
