The British transport police are appealing for information after a man threatened staff at Mile End Tube station before spitting on a member of the public on Thursday morning.
The Transport Salaried Staffs Association said the man, who did not have a ticket, demanded that the station staff open the barriers. Staff asked him to step back so they could safely social distance, but he became aggressive and swore at a female customer who intervened, and spat at her.
The British transport police attended the scene and conducted a full search of the area but the man was not found.
Transport for London have said they appalled that anyone could consider spitting at someone else especially during a national health emergency.
