Olympian Grant Hackett has reportedly been arrested on the Gold Coast.

The ‘Courier Mail‘ is reporting that he has been taken into custody in a watch-house in Southport, although it is unclear at this stage what for.

His father Nev has told the media the arrest was over “mental health issues” but has declined to add any further comment at this time, although 7 News is reporting that witnesses are saying he was ‘going off’ at his parent’s house:

7 has released video of a spaced-out looking Hackett in cuffs in the back of a cop car.

He was reportedly asleep when the police arrived at his parents’ house in Mermaid Beach.

More on this as it develops.
