Ted Terry, 59, is accused of calling Amarjit Talafair a “fucking Paki” and attacking him following a dispute over a cigarette outside a City of London pub.
Stephen Niland, 36, and Tudor Musteata, 47, are also accused of hurling racist abuse at Mr Talafair on March 22 last year.
The Old Bailey has heard Terry later got into a confrontation with Bakeba Mansuila, a cleaner at Fenchurch Street station, and allegedly called him a “black c***”.
Giving evidence, railway station worker David Bridson told the jury he had witnessed the second fracas. Mr Bridson said he saw Terry take the bottle of rum Mr Mansuila had been drinking from and make racist threats towards him. The witness said: “The threat that I heard was that he (Terry) was going to a smash a bottle over his head and he called him a black c***.
Mr Bridson claimed that on March 28 he had seen the defendant at Fenchurch Street station. He claimed to have overheard the defendant saying on his mobile phone: “When the police call, tell them I never said those things”.
Earlier, alleged victim Mr Talafair told the court Terry had at first approached him using a fake Eastern European accent to ask for a cigarette. The complainant admitted that he had called Terry a “fat bald p****” but denied using the words “Russian c***” and “I will cut you” during the stand-off.
During the attack, he said Terry tried to headbutt him. The trial continues.
