Fare Dodgers: At War with the Law

Transport for London investigators go on the trail of a fare dodger they suspect has avoided paying for more than 200 journeys. And officers board Hounslow trains - a hot spot for fare evasion.

The hunt is on in Surrey for a suspect thought to have evaded close to £20,000 of fares in one of South Western Railway's biggest ever fraud cases. And Harry has a run in with a barrier basher.

Investigators seek a fare dodger thought to be scamming TfL, racking up over 5,000 pounds in unpaid fares. A man caught without a valid ticket is more focused on finding the loo than cooperating.
