Officers from the Counter Terrorism Policing Network are continuing to speak to Charlie Rowley about his recollections prior to him falling ill.
As a result of this, specialists began removing two bins from a cordoned-off area behind shops in Catherine Street, Salisbury, at approximately 11.00hrs this morning, Thursday, 2 August. The bins will be taken to the Defence Science and Technology Laboratory at Porton Down for analysis.
The advice from Public Health England remains that the risk to the public is low.
Police searches are ongoing at a number of sites, including the Queen Elizabeth Gardens in Salisbury which has been identified as a location that Dawn Sturgess and Charlie Rowley had visited prior to them falling ill. As a highly precautionary measure, the park is subject of an extensive search to ensure that there is nothing of investigative relevance at that location and to provide confidence to the public that it is safe to use the area when it is reopened.
The town path in Salisbury was reopened to the public on Tuesday, 31 July.
Officers from the investigation team completed their work inside John Baker House and the scene was handed back to colleagues from Wiltshire Police on Friday, 20 July.
