Mr Navalny was seized after returning to Russia on Sunday and is now being detained for 30 days. In August he nearly died after being poisoned with Novichok nerve agent, the same substance used in the 2018 Salisbury poisonings.
He later accused president Putin of being personally implicated in the attack.
According to Russian prosecutors Mr Navalny was detained after violating parole terms imposed on him as part of a suspended sentence for embezzlement.
However, the prominent Kremlin critic has always alleged the charges were politically motivated.
He faces a hearing on January 29 to discover whether he will be forced to serve his three-and-a-half-year suspended sentence.
Crowds of Mr Navalny’s supporters gathered outside Vnukovo airport in Moscow on Sunday to welcome Mr Navalny’s return.
However, his plane was diverted at short notice to another Moscow airport, with supporters alleging this was in response to the number of activists who turned out.
Speaking on BBC Newsnight Vitaly Milonov, an activist within Putin’s United Russia party, suggested Britain was using false Novichok poisoning claims to attack the Russian government.
He said: “It’s so popular to call someone poisoned by Novichok.”
Five Organisation for the Prohibition of Chemical Weapons (OPCW) laboratories confirmed Novichok had been used in the attack.
A later OPCW report alleged a new strain of Novichok was used, which has yet to be listed as a controlled substance by the Chemical Weapons Convention.
Following the poisoning six senior Russian intelligence officials were subjected to sanctions by the UK and EU.
Mr Navalny later recorded and released a telephone conversation with one of the Russian intelligence operatives he alleged had been involved in the attack.
The agent claimed Novichok had been smeared on Mr Navalny’s underwear whilst he was at a hotel in Tomsk.
On March 4 2018 Sergei Skripal, a Russian double agent for British intelligence, his daughter and a police officer were poisoned with Novichok in Salisbury.
All three survived after receiving hospital treatment.
The Kremlin was blamed by the British government and 153 Russian diplomats were expelled across western countries.
However, in June a British couple, Dawn Sturgess and Charlie Rowley were poisoned in nearby Amesbury and Ms Sturgess later died.
Police concluded they were poisoned by the same Novivhok nerve agent used in the Salisbury attack.
