Vandals attacking Ulez cameras have run up a repair and replacement bill of up to £10 million in only six months.
The estimated total comes as Transport for London (TfL), which runs the Ultra Low Emission Zone (Ulez), is now being forced to hire security guards to protect engineers installing and repairing cameras and mobile Ulez camera vans.
Latest figures show that from April 1 to Oct 31 this year, the Met Police recorded 220 cameras stolen and 767 cameras damaged.
