Anti-lockdown protestor Piers Corbyn, 74, was filmed peeling off stickers as he walked up and down the Victoria Line service between Green Park.
The signs warned passengers to social distance and also that they could be fined for not wearing face coverings.
Piers slammed Boris Johnson and world leaders in a rant after lockdown easing was pushed back from June 21 to July 19 following the rise of Covid variants in the UK.

He told commuters and tourists: ‘They did not keep their distance at the G7 did they?
The outspoken brother of the former Labour leader removed two stickers from a window of the carriage and three more from glass barriers near the doors.
He added: ‘Boris lied to us so we are taking these down ourselves.’
Some passengers looked on in bemusement as he stuffed the signs into an orange carrier bag with the help of another man on Friday.
He was not challenged by fellow passengers in the video, who were mostly wearing masks to prevent the spread of covid-19.

The video was also met with outrage on Twitter where users called for the British Transport Police to take action.
A representative for Unison Worcestershire Community Health tweeted: ‘I am quite angry by this sort of behaviour. At the very least it’s criminal damage but perhaps more importantly it foes against a lot of what I do as a nurse.’
Another Twitter user wrote: ‘Looks like theft and vandalism to me. I hope Met Police have seen that video.’
Stephen Maskrey wrote: ‘As he’s mixing with so many people he may find out how bad covid-19 is.’

Piers has been arrested at least twice so far in 2021 for repeatedly breaching lockdown and covid restrictions to protest against lockdown measures.
On January 2, he was among 17 people who were arrested for breaching Health Protection Regulations at the demonstration at Speaker’s Corner, in Hyde Park.
A crowd of between 200 and 300 people gathered to protest against lockdown restrictions and their civil liberties being curtailed.
It came after Piers was fined and arrested on New Year’s Day after leading a New Year’s Eve anti-lockdown protest near the London Eye, in the centre of the capital.
Piers posted a video of what was dubbed the ‘NYE Party of Parties’ on his Twitter feed, proclaiming: ‘TOTAL SUCCESS! #NYEPartyofParties by London Eye.
‘Over 1000 defied all threats +chanted #LetLondonLive! & #Corbyn4London after I announced I will stand for Mayor! Thank you +well done all!’
The conspiracy theorist has now been arrested at least five times since the start of the coronavirus pandemic and has received fines totalling more than £10,000.
