TikTok influencers are brazenly showing London Underground passengers how to illegally travel for free by 'bumping' through the station ticket barriers.

Young men are filming themselves laughing and joking with each other as they push through the wide-aisle gates in videos liked by hundreds of thousands of viewers.

The gates, which were first installed in 2008 at a cost of £12million, are normally used by wheelchair users, older people, parents with children and travellers with luggage.

But they are increasingly being used by fare dodgers who either push through the gap in the middle, or quickly follow someone in front of them who touches out.

It comes amid a fare dodging epidemic on UK trains, with an official report published this week revealing staff believe the practice is becoming 'normalised' and they are struggling to cope with 'aggressive' passengers who refuse to buy tickets.
