The source said investigators have been combing through months of surveillance camera footage from UK airports and from Salisbury, where the Skripals were poisoned in an attack the British government blames on Russia.
Using facial recognition technology, authorities discovered two “fresh identities” — individuals not known to have been spies or used in other attacks — the source added.
Investigators have crosschecked that information with the manifest of the commercial flight on which the suspects were believed to have left Britain soon after the attack in March. Those names were aliases, the source said, and police have not yet revealed them.
Britain’s Press Association news agency also reported Thursday that police had identified suspects in the case. London’s Metropolitan Police declined to comment.
Russia has repeatedly denied any involvement in the attack and has put forward multiple theories as to who may have been behind tt.
It is unclear where Rowley found the bottle, or whether it is the same batch of nerve agent that poisoned the Skripals.
