Detectives believe that former Russian spy Sergei Crispaul, who lives in the United Kingdom, was attempting to kill his daughter with chemical VX nerve gas.
Assistant Commissioner of Police of the Anti-Terrorism Branch of the United Kingdom, Mark Rowley, said that the first police officer visited the spot. His condition is serious.
On Sunday afternoon, Sergei Krispal (66) and his 33-year-old daughter, Iulia, were found unconscious on the bench of a shopping mall in Salisbury city. Krispal worked in the Russian intelligence.
But he was convicted of working for the UK. Later, he was released under the Spying Exchange Act and started living in the United Kingdom.
