"We know who these people are, we have found them", Mr Putin said.
Police and prosecutors last week said Alexander Petrov and Ruslan Boshirov had been identified as members of the GRU, Russia's military intelligence service. "There is nothing special and criminal about them, believe me", Putin said, adding that the two were civilians.
British authorities have issued European arrest warrants for Alexander Petrov and Ruslan Boshirov, two suspected members of Russian military intelligence, the GRU.
British Prime Minister Theresa May said last week that the two men who carried out the nerve agent attack were Russian spies.
The duo had entered Britain on genuine passports, prosecutors said, while British Prime Minister Theresa May described them as military intelligence officers nearly certainly acting on orders from high up in the Russian state. "We'll see in the nearest future".
State TV channel Rossiya-24 claimed it had spoken to Alexander Petrov, who, along with Ruslan Boshirov, has been named by United Kingdom prosecutors as a prime suspect in the nerve agent attack.
"The president has not communicated with them", Peskov said.

Mr Rowley is seriously ill and was readmitted to hospital earlier this month after going blind.
Britain and more than two dozen other countries expelled a total of 150 Russian diplomats, and Russia kicked out a similar number of those countries' envoys.
