Police are looking to trace two men and a woman in connection with a violent assault on London Underground staff.
Officers would like to identify them after Transport for London (TfL) staff were attacked at West Ham Underground station in London on Thursday night..
At around 7.40pm on Wednesday night (18/09), two young men and a woman barged through the ticket gates and into the station.
The woman was smoking and was asked to leave by TfL staff, but the two men accompanying her threatened and lunged towards staff to try and attack them.
The victim along with another member of TfL staff quickly retreated to the staff office for their own safety, but the group pushed open the door and the two men punched staff multiple times.
Other TfL staff received punches whilst trying to separate the men from his colleagues, before all parties then left the station.

Vernon Everitt, Managing Director of London Underground, said: “This sickening attack on our colleagues at West Ham station will not be tolerated.
“We want the perpetrators brought to justice and will work with the police to do everything we can to apprehend them and then prosecute them to the fullest extent of the law.
“We call on anyone who has information on this horrific attack to get in touch with the British Transport Police.”
PC Luke Dear from British Transport Police, said: "This was a shockingly violent and determined attack on staff who were simply trying to do their job, they should be able to do their job without the fear of an assault.
"Thankfully they weren't seriously injured but of course were left incredibly distressed by this terrifying ordeal.
"We believe the men and the woman in the CCTV images may have information which could help our investigation, and we'd like to speak with them as soon as possible.
