London Underground: Catching the Tube’s fare-dodgers
Transport for London (TfL) has deployed enforcement officers across the network to tackle anti-social behaviour and fare evaders - estimated to cost about TfL £150m a year.
Over a period of four weeks, it says it removed 47 passengers who refused to comply with its rules and were obstructive or threatening towards staff.
The officers have also been catching people who do not pay for their travel, reporting 132 passengers for prosecution for breaching bylaws.
BBC Radio London’s Eddie Nestor went behind the scenes with the enforcement officers to take a look at the challenges they face.
