Around 2,570 automatic number plate recognition cameras are being placed across London ahead of the expansion on August 29.
Anyone who drives a vehicle in London that does not meet emission standards will have to pay £12.50 a day to drive.
Pictures posted on social media seem to show wires on the ULEZ cameras in Masons Hill left slashed.
The act has caused a great stir in the comments section, with people celebrating the act.
One person commented: “Good job.”
Another person said: “Fantastic, Well-done Bromley heroes.”
A spokesperson for Transport for London said that vandalism on its network is “unacceptable.”
It added that all incidents will be reported to the police for an investigation.
More images have surfaced on social media showing ULEZ cameras in Knee Hill, Abbey Wood, also left damaged.
At the time on March 29, a spokesperson for Mayor of London said that it is “deeply disappointing” to see opposition to the policy.
They added that this “petty” vandalism of London’s “essential” transport infrastructure is completely “unacceptable”.
There are currently more than 300 cameras that have already been installed across outer London boroughs.
Five councils have won the first stage of a legal challenge over Sadiq Khan’s expansion plans.
Bexley, Bromley, Harrow, Hillingdon – along with Surrey County Council teamed up to fight the mayor’s plans.
It was announced that the case will be going to High Court on two grounds – the failure to follow statutory procedures and failure of consultation over the scrappage scheme.
It is reported that the case is set to be heard in July.
We have contacted the Mayor of London’s office for a comment regarding the damaged cameras in Bromley.
