A murder trial has been shown CCTV of a man throwing his hands into the air and clawing at his face in a lift shortly after his girlfriend had plunged to her death from their apartment balcony.
Simon Gittany, 30, is accused of throwing Lisa Harnum from the 15th floor flat at the boutique Hyde apartment building in Sydney in July 2011.
He was captured on security cameras apparently acting in a highly agitated manner moments after the 30-year-old Canadian's death.
Gittany was seen holding his head in the apartment lift Gittany was wearing pyjamas when he walked into the lift in the building and began gesticulating wildly and putting his hands to his head.
When the doors opened on the ground floor he ran into the lobby, his trial at the Supreme Court was shown.
Earlier in the trial, footage showed Gittany allegedly struggling with his girlfriend.
Lisa Harnum was killed by her 'abusive' boyfriend, the prosecution claims Gittany has pleaded not guilty to her murder and will give evidence next week.
He says she climbed onto the balcony railing and then fell.
Crown Prosecutor Mark Tedeschi QC said the video of the couple wrestling with each other was taken from a secret pin hole camera outside the couple's apartment.
The balcony from which Ms Harnum fell It allegedly shows Ms Harnum walking out of the front door before being grabbed in a headlock and pulled inside.
She fell to her death 69 seconds later and Gittany left the flat 14 seconds after that, the court was told.
He is then caught on camera leaving the apartment with no shirt on. He returns seven seconds later and leaves again, this time wearing a white top.
Gittany arrives at court in Sydney with his new girlfriend After taking the lift to the lobby, another camera captures him running outside to where Ms Harnum's body is on the pavement.
The court was then played CCTV footage of her body hitting the ground - video the judge said was too distressing to be released.
It is alleged Gittany was controlling, abusive and secretly monitored his girlfriend's phone calls and emails.
The court heard he was angry because she wanted to leave him.
The trial continues.
