A quarter of all new Ulez cameras in the expanded London zone have already been damaged or are missing, according to new data.
The controversial expansion of the capital’s ultra-low emission zone (Ulez) came into effect this week and now covers suburban areas.
Motorists who drive in Greater London in a vehicle that does not meet minimum emission standards must pay a £12.50 daily fee or risk a fine.
But at least 450 of the 1,762 new cameras meant to monitor the zone are either missing or have been damaged, a crowd-sourced map suggests.
Watch: Hundreds of attacks on ULEZ cameras recorded by police
Around 20% of the cameras are currently not functioning in the whole of Ulez but the situation is worse in outer London, where 25% of cameras are out of action, according to Julie's Ulez Map.
The damaged cameras are mainly located in the south and south-east areas of London, with high rates of vandalism reported in Bromley, Lewisham, Sutton, and Bexley.
It was previously revealed, Transport for London (TfL) was facing a major challenge as a group of protesters who were sabotaging the cameras.
The devices have been vandalized in various ways, including removal, wire-cutting, paint-spraying, and tearing down by people who call themselves "blade runners".
The Metropolitan Police said it had recorded 288 crimes relating to the cameras as of 1 August and released an image of a suspect.
On Wednesday, the Met said in “recent weeks there has been an increase in criminal damage and theft to Ulez cameras and infrastructure”.
It added there were currently hundreds of reports of criminal damage being investigated.
It follows The Daily Mail's publication of quotes from Tory MP Iain Duncan Smith, stating that he would be "happy" for his constituents to "cement up the cameras or put plastic bags over them".
This was in response to his belief that his constituents were facing an unwelcome imposition, having been misled about the situation.
However, Sir Iain later clarified to the Evening Standard that he "does not condone law breaking of any kind".
TfL said in a statement: "Vandalism on our network is unacceptable and all incidents are reported to the police for investigation.
"Criminal damage to Ulez cameras puts the perpetrators at risk of prosecution and life-changing injuries, while simultaneously risking the safety of the public.
"Camera vandalism will not stop the Ulez operating London-wide. We have an extensive camera network which is sufficient to support the effective operation of the scheme.
"Anyone driving a non-compliant vehicle within the expanded zone will be detected, and we advise everyone to check whether their vehicle is compliant and to consider the various support that is available."
