A man has been arrested after an assault which police believe is connected to an earlier incident of racist abuse.

The 33-year-old man was arrested after an 18-year-old man was attacked at a bus stop on Great Junction Street, Edinburgh around 3.45pm on Thursday.

It is understood the teenager had intervened after another man was allegedly subjected to racist abuse as he boarded a number 22 bus.

The 18-year-old was left uninjured after the incident, which took place near the Ladbrokes on the street.

Police have now asked for any witnesses to come forward.

PC Christopher Paul said: "A man, believed to be boarding a number 22 Lothian Bus, was subject to racial abuse shortly before the assault and I'd urge him to come forward.

"This type of behaviour is absolutely unacceptable and we're also asking any witnesses, or anyone with information which can help, to get in touch.

"There was about three adults in the area of the bus stop at the time of these incidents who we're particularly eager to speak to."

Anyone with information is urged to contact Police Scotland on 101 or contact Crimestoppers anonymously on 0800 555 111.
