Police have released CCTV images after five Asian men were racially abused and threatened with violence on a train to Barking.
They boarded a train at Grays in Esses at around 8pm on July 21, along with four other men who had previously trespassed on the track.
During the journey the four men began making racist remarks to the victims, who were in their 20s.
PC Greig Watkins, from the British Transport Police (BTP), said: “As the train arrived at Barking, another man, who we believe knew the suspects, boarded the service and began to threaten the victims with violence.”
Police were called and a 19-year-old from Woodford Green was arrested on suspicion of a public order offence. He has been released on police bail until August 27.
Officers now want to speak to the four men pictured, who are believed to be from the Grays area.
Pc Watkins added: “Violence and verbal assaults on the rail network is simply not accepted.
“No one should be subjected to such vile behaviour, and we will do all we can to track the men responsible and bring them to justice.
“If you know any of the men, or are indeed one of those pictured, come forward and help officers in this investigation.”
Call the BTP on 0800 405040 quoting background reference B13/LNA of 08/08/2013. Information can also be passed to the independent charity Crimestoppers, anonymously, on 0800 555 111.
