Moscow (CNN) A Russian agent sent to tail opposition leader Alexey Navalny has revealed how he was poisoned in August -- with the lethal nerve agent Novichok planted in his underpants.
Konstantin Kudryavtsev revealed he traveled to Omsk in Siberia to try to clean up evidence after Alexey Navalny was poisoned.
He was talking to Navalny himself, who almost died after being poisoned in August.
Oleg Tayakin opened the door to CNN but closed it as soon as he was asked about his role in tailing Navalny.
The Bellingcat-CNN investigation found that the FSB toxins team of about six to 10 agents trailed Navalny for more than three years.
Alexey Navalny, speaking brusquely and urgently, convinced Kudryavtsev he was an official reviewing the operation.
Navalny and his team have several times demanded that his clothes be returned to him , but Russian authorities have refused. »
