British Transport Police is appealing for information after three youths racially abused a passenger at Bromley South station.
The victim, a 41-year-old black man from Orpington, was on platform four waiting for a train to St Mary Cray when he was approached by three men.
They are described as white and aged between 16 and 20-years-old
They began to swear at him and used racially abusive language, which he found very intimidating.
When the train arrived the victim got on a separate carriage to his abusers but they all got off at St Mary Cray station and the racial abuse continued.
Investigating officer PC Neil Allison said: “The victim was understandably very shaken by his experience, and we are determined to find those responsible.
“Anti-social, racist or violent behaviour has no place on the railway and passengers should feel able to use the network without fear of becoming a victim of crime.
“Anyone who witnessed the incident, or who has any information about what took place, should get in touch.”
The incident started at around 12.50am on March 29 and BTP has only just appealed to the News Shopper for help.
Anyone with information is asked to call British Transport Police on 0800 405040 quoting B22/ LSA of 17/04/2013.
Alternatively, contact Crimestoppers anonymously on 0800 555111.
