LONDON (AP) — British police said Tuesday they are charging a third Russian suspect in the 2018 nerve agent attack on a former Russian agent in England.

Scotland Yard said prosecutors believe there is sufficient evidence to charge a man known as Sergey Fedotov with conspiracy to murder, attempted murder, possessing and using a chemical weapon, and causing grievous bodily harm.

Former Russian spy Sergei Skripal and his daughter, Yulia, were targeted in a nerve agent attack in 2018 in Salisbury, England, that British authorities said had almost certainly approved been “at a senior level of the Russian state.” Moscow has vehemently denied the allegations.

Police said they have evidence that “Sergey Fedotov” is an alias for Denis Sergeev, a member of the Russian military intelligence service known as the GRU.
