Ian Morbin, 25, who earns at least £24,000 a year, was caught on camera last week shouting at an elderly man whose arm had become trapped in a Tube train door at Holborn station.
This caused more commuters to come forward with complaints...
BBC employee Andrea Lee said Mr Morbin screamed at her: "You're my f***ing problem." Ms Lee, 26, had complained last month about his treatment of another elderly passenger but said Mr Morbin turned on her angrily and "started screaming and chased me down the platform"...Security officer Liam Felton, 29, said he was told to "walk under a bus" by Mr Morbin earlier this month. Mr Felton, from Stoke Newington, added: "I went to tell him the barrier wasn't working and he just went off on one at me."
