South Australian police are interviewing Hawthorn coach Alastair Clarkson over his confrontation with a fan outside the team hotel in Adelaide last month.

Police have travelled to Melbourne and were speaking to Clarkson on Monday morning, after beginning their investigation of the incident two weeks ago.

Clarkson clashed with a Port Adelaide supporter while walking back to the team's hotel from Adelaide Oval after Hawthorn's game against the Power on the night of April 25.
