Three men have been arrested on suspicion of racially assaulting an Indian origin student on a train from London to Derby.
Saurabh Srivastava, 24, was travelling from London St Pancras to Derby when he said six men started racially abusing him.
Srivastava is a student at Derby University.
He said he was "humiliated" after he was covered in fire extinguisher foam and beer during the attack recently, according to reports in Derby.
A British Transport Police spokesperson said that two men from Chaddesden, aged 26 and 32, and a 27-year-old man from Belper, were arrested following an appeal for witnesses.
They have been released on bail until June.
