An Australian man was beaten so badly that he suffered complete memory loss for 22 days after the attack and 18 months later struggles to remember details of the six months leading up to the attack.

Scott Lillicrap, 35, was returning home from a soccer match when he was robbed, beaten and stomped on at the Sunnybank railway station in southern Brisbane, Australia, on July 30, 2006, according to a report from Australian news agency AAP.

A Brisbane District Court was told that the man was beaten and dragged through the station's car park and dumped near a charity bin before witnesses called an ambulance.

Lillicrap spent weeks in a coma, suffered multiple fractures to his face and post-traumatic amnesia for 22 days. A blood clot caused one of his lungs to collapse.

Lillicrap has no memory of the attack itself.

The teens responsible for the attack are now aged 16, 17 and 18. They each pleaded guilty late last year to grievous bodily harm with intent.
