A crowd chanted the racial slur "Paki, Paki" at a man before pushing and shoving him on a Belfast street, a court heard.
The group were standing on the Ormeau Road in the south of the city on March 7 when they targeted the victim.
Details emerged as one of the crowd, Jamie Scott, was convicted at Belfast Magistrates' Court on Thursday for his part in the incident.
The 20-year-old pleaded guilty to assaulting the man after the group had racially taunted him.
Offended by the remarks, the victim confronted the crowd but was further abused.
It was claimed that Scott, of Belfast Road in Saintfield, Co Down said: "F*** you, you b******, I will drop you."
As the victim turned to walk away he was pushed and subjected to more racist slurs.
Scott was arrested a short time later and subsequently picked out during an identification procedure.
According to his lawyer he regrets his "completely out of character" behaviour and wanted to apologise to the victim.
"He had a large amount of alcohol taken," the barrister said.
"There was a group mentality situation where he was in a group which seems to have egged each other on."
A prosecution lawyer said the incident earlier this year was aggravated by the level of hostility shown.
Scott was ordered to complete 80 hours community service.
Imposing the order, District Judge George Conner said: "This was a shocking incident, and I have no doubt (it was) very frightening for the injured party."
