A female Tube driver was attacked when fighting passengers on a late-night train forced their way into her cab, union bosses said today.

They screamed at her and blocked her from closing the driver’s door on the Northern line service from King’s Cross, just before midnight on Saturday. Despite this, she managed to bring the train safely into Angel station.

A British Transport Police spokesman said: “A 54-year-old man from Southwark and a 28-year-old man from Seven Sisters were arrested on suspicion of affray, but have now been released under investigation as enquiries continue.”

Drivers’ union Aslef has threatened strike action unless London Underground increases security. Aslef’s Finn Brennan said: “People became involved in a fight. Some forced their way into the driver’s cab and attacked her, preventing her from closing the door.

"She has been left badly shaken, but suffered no serious physical injury. We fear it is only a matter of time before someone is seriously hurt unless LU makes drivers’ cabs secure.”

A TfL source disputed the claim the driver was attacked.

Nick Dent, Director of Line Operations, Transport for London, said: “We take the safety and security of our staff extremely seriously and understand this would have been a distressing incident to be caught up in. Customers were seeking help after an earlier altercation on the tube.

"We are offering the member of staff involved our full support and continue to work closely with the British Transport Police to fully investigate the circumstances of the incident.”
