Grant’s father Nev addressed media Thursday afternoon and told the Courier Mail:

“I do not know where he is.”

Nev said Hackett was no longer at Pindara Private Hospital.

Queensland Police said they could not confirm whether Hackett was reported missing.

The 36-year-old took to social media early Thursday posting a photo of himself with a bruised and bloodied face stating:

“My brother comments to the media... but does anyone know he beat the sh*t out of me. Everyone knows he is an angry man.”

A family member reportedly took out a court order against Hackett following an incident which saw the Olympian treated for a facial injury.

The post follows a dramatic Wednesday in which Hackett was arrested at his parents Gold Coast home after becoming a “danger” to himself.
