A video posted on Facebook appears to show a man in Swindon Wilts, making offensive n-word comments.

A 26-year-old man from Swindon was arrested on Wednesday on suspicion of racially aggravated provocation and remains in custody.

The commotion causes many shoppers to stop in their tracks and watch the man before he is then chased off down a nearby street.

The crowd had dispersed by the time police arrived at the scene.

Sergeant Max Whyte, from the Swindon town centre policing team, said: "This was a particularly horrible incident which happened in a very public place.

"I want to reassure the people of Swindon that we will never tolerate anti-social behaviour like this nor any similar incident and any sort of behaviour like this will be dealt by us very quickly - this is never acceptable in our society.

"Also, we would like to speak to anyone who witnessed this incident; there were lots of people in town yesterday and we know many people saw what happened. If that was you please come forward and speak to me or one of my team."
