Salisbury nerve agent attack and Amesbury poisonings

On 4 March 2018, Sergei Skripal and his 33-year-old daughter Yulia (who was visiting from Moscow) were found unconscious on a public bench in Salisbury, poisoned by a nerve agent from the Novichok family. Novichok means ‘newcomer’ in Russian.

Three people were admitted to hospital and a further person treated as an out patient. The police identified 131 people who could have come into contact with the nerve agent but none have so far shown any symptoms.

Police are examining 5,000 hours of CCTV footage and 1,350 items that have been seized.

It is one of the largest and most complex investigations undertaken by British counter terrorism policing.

The Russians strongly deny any involvement.

A further incident happened on 30 June with two people falling ill in Amesbury – Charlie Rowley, 45, and Dawn Sturgess, 44. Sadly, Dawn later died as a result of the poisoning.

Impact on the city

Nine businesses were closed as a result of the incident and businesses near to the cordons saw footfall reduce between 60-80%. Footfall across the city centre was down by an average of 15% in April 2018.

Who is Sergei Skripal?

Sergei Skripal is a retired Russian military intelligence colonel who was sentenced in 2006 to 13 years in prison, accused of spying for Britain. He was a double agent for the UK’s intelligence services (MI6) during the 1990s and early 2000s.

In December 2004, he was arrested by the FSB and later tried and convicted of high treason and sentenced to 13 years in prison. In July 2010 he was one of four prisoners that Moscow swapped for their spies in the US.

In 2011 he moved to Salisbury and bought a house in Christie Miller Road.

However, anyone who was in the area and is concerned because they feel unwell, should dial 111 or 999 depending on the severity of their symptoms.”

Dr Jenny Harries, Deputy Medical Director at PHE said: “Rigorous scientific analysis has been ongoing and we have learnt that there has been some limited contamination in both The Mill pub and Zizzi restaurant in Salisbury. Anyone who visited The Mill pub or Zizzi restaurant, where the 2 affected individuals were, can be reassured that this limited exposure will not have harmed their health to date. However, there may be a very small health risk associated with repeated contact with belongings which may have been contaminated by this substance. We therefore recommend that a precautionary approach is taken and advise people to clean the clothes they were wearing and any possessions they had with them.” The public were advised to wash clothes and wipe items with baby wipes but to wait on further instruction for dry clean items.

12 March
Prime Minister Theresa May said to the Commons: “It is now clear that Mr Skripal and his daughter were poisoned with a military-grade nerve agent of a type developed by Russia.”

“This is part of a group of nerve agents known as ‘Novichok’.”

“Based on the positive identification of this chemical agent by world-leading experts at the Defence Science and Technology Laboratory at Porton Down; our knowledge that Russia has previously produced this agent and would still be capable of doing so; Russia’s record of conducting state-sponsored assassinations; and our assessment that Russia views some defectors as legitimate targets for assassinations; the Government has concluded that it is highly likely that Russia was responsible for the act against Sergei and Yulia Skripal.”

“Mr Speaker, there are therefore only two plausible explanations for what happened in Salisbury on the 4th of March.

“Either this was a direct act by the Russian State against our country.

“Or the Russian government lost control of this potentially catastrophically damaging nerve agent and allowed it to get into the hands of others.

“The Foreign Secretary has summoned the Russian Ambassador to the Foreign and Commonwealth Office and asked him to explain which of these two possibilities it is – and therefore to account for how this Russian-produced nerve agent could have been deployed in Salisbury against Mr Skripal and his daughter.

“My Rt Hon Friend has stated to the Ambassador that the Russian Federation must immediately provide full and complete disclosure of the Novichok programme to the Organisation for the Prohibition of Chemical Weapons.

“And he has requested the Russian Government’s response by the end of tomorrow.”

He said: “We were able to identify it as novichok, to identify that it was military-grade nerve agent.

“We’ve been keeping you updated on the condition of Yulia and Sergei, whilst respecting the right to privacy to which they – and all our patients – are entitled.

“While I won’t go into great detail about the treatment we’ve been providing, I will say that nerve agents work by attaching themselves to a particular enzyme in the body which then stops the nerves from working properly.

“This results in symptoms such as sickness, hallucinations and confusion.

“Our job in treating the patients has been to stabilise them– ensuring that the patients could breathe and that blood could continue to circulate.

“We then needed to use a variety of different drugs to support the patients until they could create more enzymes to replace those affected by the poisoning.

“We also used specialised decontamination techniques to remove any residual toxins.”
