A third Russian national has been charged in the 2018 nerve agent attack of a former Russian agent in Salisbury, England, British police said on Tuesday.

The Metropolitan Police said on Twitter that Denis Sergeev, who used the name Sergey Fedotov as an alias, was charged with conspiracy to murder, attempted murder, grievous bodily harm, possession, and use of a chemical weapon.

The case dates back to March 2018, when former Russian agent Sergei Skripal and his daughter, Yulia, were targeted with exposure to the nerve agent novichok.

The father and daughter survived the attack, but a British woman, named Dawn Sturgess, later died after being exposed to the agent and her partner, Charlie Rowley, was left seriously ill.

Former Wiltshire Detective Sergeant Nick Bailey, who was the first police officer to enter the Skripal home after the attack, also fell ill.

Alexander Petrov and Ruslan Boshirov were previously charged in the case.

Metropolitan Police has issued arrest warrants for all three suspects, the agency said in a press release.

"I congratulate the police and all those involved in identifying this third individual and in developing the evidence leading to charges against him," former Prime Minister Theresa May, who led the UK government at the time of the attacks, said in a statement. "This is further confirmation that responsibility for this attack lies firmly in the hands of the Russian state. I urge the UK government to do all it can to bring the individuals concerned to justice."
