Humza Yousaf, Scotland's Minister for External Affairs and International Development, was allegedly verbally abused in Glasgow city centre earlier this month.
The incident happened when the politician, an SNP MSP for Glasgow, was selling the Big Issue outside Queen Street station to raise awareness of homelessness as part of International Street Paper Vendor Week.
Police Scotland said a 30-year old man has been arrested in connection with an alleged racial breach of the peace following an incident outside Queen Street station in Dundas Street at around 4.45pm on Friday February 7.
He is being held in police custody and is expected to appear at Glasgow Sheriff Court tomorrow.
A report will be sent to the procurator fiscal.
