Navalny was poisoned with Novichok at his hotel, not at the airport

Novichok, the nerve agent used to poison Russian opposition leader Alexei Navalny was detected on an empty water bottle from his hotel room in the Tomsk. His team now believes that he was poisoned in that hotel room, not at the airport as they had initially suspected.
In a video posted on Navalny's Instagram, his aides are seen collecting items from the hotel room an hour after they learned he had fallen sick in suspicious circumstances.
Navalny fell violently ill on a domestic flight in Russia last month and was transferred to Berlin for treatment. Germany says he was poisoned by a Novichok nerve agent, while Russia says it has seen no evidence he was poisoned.
