The final moments of Brazilian student Roberto Laudisio Curti's life have been shown to a Sydney coroner.
Video footage of a Taser being discharged at the 21-year-old man in March this year was played in the Coroner's Court in Glebe today.
The footage, described by counsel assisting the coroner, Jeremy Gormly, SC, as "distressing", was not watched by the dead man's sisters, who were not present in court at the time.
It showed Mr Laudisio Curti falling to the ground and rolling around in pain, as an officer shouted, "Stop resisting or you will be Tasered again."
Mr Curti stopped breathing shortly afterwards and was pronounced dead at the scene about 6.10am.
Mr Laudisio Curti was pursued through the CBD in the early hours of March 18, after reports of a robbery at a King Street convenience store.
CCTV footage showed him running through the city, barefoot and bare-chested after he discarded his T-shirt, socks and shoes.
He was chased by several officers after he allegedly stole two packet of biscuits from a convenience store and was brought down by a Taser discharge.
The court has heard police used their Tasers 14 times, although not all of them hit the young man or were effective.
"Superhuman strength from LSD"
Capsicum spray, handcuffs and a baton were also used to restrain Mr Curti, who was having an adverse reaction after he took a small amount of the drug LSD the previous night during St Patrick's Day celebrations.
The drug left him paranoid, restless, and possessing "superhuman strength" as he tried to avoid arrest, the court heard earlier.
The inquest is examining the manner and cause of Mr Laudisio Curti's death, the lawfulness of the arrest and the degree of force used by the 11 police officers involved.
"There is no suggestion Roberto was doing anything but endeavouring to get away from police," Mr Gormly said.
"There is no suggestion he had a weapon ... There is no suggestion he struck or assaulted any person, although police believed he might."
An autopsy carried out on Mr Curti was unable to establish a cause of death, Mr Gormly said.
"By all accounts, Roberto, known as Beto by his family, was an impressive and promising young man," he said.
The 21-year-old was a talented soccer player who had completed a degree and was living with his sister in Sydney while he studied English, the inquest heard.
"The death of Roberto is tragic for his family members, both those here in Australia and in Brazil," Mr Gormly said.
"His death however has also caused concern and widespread comment here in Australia.
"It is a matter that raises questions of public importance."
The inquest will hear evidence that during the police chase and ensuing struggle, "a total of 14 Taser discharges" were applied to Mr Laudisio Curti.
"It is clear that many did not hit him or hit him in a way that was effective," Mr Gormly said.
"Nevertheless, it is a very large number of uses which requires examination."
Throughout his opening remarks, Mr Laudisio Curti's sisters wiped their eyes with tissues.
State Coroner Mary Jerram had earlier expressed her condolences for their brother's death.
The inquest continues.
