Transport for London investigators confronted a woman at Ilford station in East London after alleging she made more than 400 journeys with a scam contactless card, leaving a shortfall of £3,160.40 in unpaid fares, footage from a Channel 5 documentary shows.

The episode of Fare Dodgers: At War With The Law, which aired on Channel 5 and is available to stream on 5, follows two TfL investigators who say they tracked the card’s use for weeks and cross-referenced dates, times and stations with CCTV images to identify the passenger. The woman was stopped on the Elizabeth line and taken into a private room, where an investigator identified as Lisa told her: “We have been following you, yes you, for quite a while.”

Investigators presented CCTV stills of the woman passing through ticket gates and told her she owed TfL £3,160.40. According to the programme, she provided her name and address but refused to hand over the bank card investigators said had been used, leading them to caution her rather than arrest her. The team said further CCTV from Notting Hill Gate Underground station would be required to progress the inquiry and that the investigation would continue.

The documentary includes other confrontations. One segment shows a university law student who broke down after being stopped at Clapham Junction and saying, "my life is finished," when confronted by an inspector. Another clip features a passenger stopped at Harold Wood station who allegedly avoided about £1,650 in fares over nearly 250 journeys. Programme footage also includes a passenger who was finally apprehended at London Waterloo after evading almost £20,000 in ticket costs by buying a short portion of a longer journey at Vauxhall.

Transport for London and the wider rail industry say fare evasion has risen since the opening of the Elizabeth line in 2022. A Freedom of Information response to the Evening Standard cited in the programme showed losses of about £130 million in 2022/23, rising to about £190 million in 2023/24 and reported at £188 million in 2024/25. Industry body the Rail Delivery Group has previously estimated annual lost revenue from fare evasion at between £350 million and £400 million.

The issue has provoked public debate amid a series of high-profile enforcement cases. Transport Secretary Heidi Alexander has written to train operators urging that enforcement be proportionate and not punish passengers making genuine mistakes. Alexander accepted recommendations from the Office of Rail and Road aimed at creating consistency in how passengers are treated when ticketing disputes arise and improving passenger information about tickets.

Some incidents shown on-screen have drawn criticism from campaigners and passengers who argue that enforcement can be heavy-handed in cases of confusion over fares and discount eligibility. The programme also includes footage of a passenger forcing his way through gates at Kingston station and later alleged attacks on British Transport Police officers, underscoring tensions at some stations.

London’s approach to tackling fare evasion includes investigations by TfL’s enforcement teams and cooperation with British Transport Police in more serious cases. Investigators typically seek identification and evidence such as the card alleged to have been used; refusal to comply can result in cautioning, further inquiry or referral to police depending on the circumstances and the evidence available.

Channel 5’s series follows investigations across the network and aims to show how transport authorities gather evidence and confront suspected fare dodgers. Fare Dodgers: At War With The Law is scheduled to continue on Channel 5 next Monday at 9 p.m., according to the broadcaster.

TfL and the Department for Transport did not comment in the programme; Channel 5 supplied the footage and investigators’ accounts to viewers. The case at Ilford remains under investigation, with the enforcement team planning to obtain additional CCTV footage to corroborate the card-usage data and complete their inquiry.
