The officer was involved in the response to the poisoning of former Russian spy Sergei Skripal and his daughter Yulia.
Specialist teams removed them from behind shops in Catherine Street in Salisbury at around 11am on Thursday for testing.
Russia's ambassador to the UK has suggested Sergei and Yulia Skripal may have been injected by British authorities with nerve agent.
The Medical Director at Salisbury District Hospital, Dr Christine Blanshard, issued a statement after the release of Yulia Skripal.
Two weeks since the nerve agent attack on a former Russian spy and his daughter, Salisbury is still suffering a slump in footfall.
