Despite his family's calls for manslaughter charges, Roberto Laudisio Curti's death at the hands of ''thuggish'' police will result only in assault charges for four of the 11 officers involved.

The Director of Public Prosecutions announced on Friday that there was sufficient evidence to charge two officers with common assault and two with assault occasioning actual bodily harm.

Mr Curti, a 21-year-old Brazilian studying in Australia, died on Pitt Street in the early hours of March 18, 2012, following a violent struggle with the police, many of whom had chased him down the street, acting on incorrect reports of an armed robbery.

He had earlier jumped over the counter of a convenience store in an LSD-induced psychotic state and left with two packets of biscuits.

Tasers were fired up to 14 times - nine of which hit Mr Curti - and he was restrained by seven officers using three cans of OC spray, two sets of handcuffs, a police baton and ''half a tonne'' of officers, an inquest heard in October 2012.

Mr Curti's uncle Domingos Laudisio, who raised Mr Curti in Brazil after his parents died of cancer, demanded the officers be charged with manslaughter.

''[The announcement] is a very important step ahead in order to bring justice,'' he said. ''However … a more in-depth investigation is more than needed regarding manslaughter.''

State Coroner Mary Jerram said the officers were ''thuggish'' and their ''reckless, careless, dangerous and excessively forceful'' actions led to Mr Curti's death.

Four of the five officers she recommended for disciplinary action are expected to be charged in the next week.

The most senior officer involved, Inspector Gregory Cooper, who was accused of giving contemptible evidence to the inquest, has avoided criminal charges and remains on duty.

Senior Constable Scott Edmondson, who Tasered Mr Curti twice in the back as he lay on the ground, and Constable Daniel Barling, who Tasered Mr Curti five times in ''drive stun'' mode, will be charged with assault occasioning actual bodily harm.

Senior Constable Damian Ralph, who used three partial cans of capsicum spray on Mr Curti as close as 10 centimetres to his face, and Senior Constable Eric Lim, who Tasered Mr Curti once to bring him to the ground and again when he was face-down in handcuffs, will be charged with common assault.

All four officers were moved to desk duties when they were referred to the Police Integrity Commission in November 2012.

Senior Constable Ralph still works for the State Crime Command's anti-bikie taskforce, Strike Force Raptor.

Mr Curti had been studying in Australia and living with his sister, Ana Luisa Laudisio de Lucca, and brother-in-law, Mike Reynolds, in Balmain.

Mr Reynolds said the charges against the officers ''do not adequately reflect their behaviour on the night''.

''[Mr Curti's] death has had a massive impact on the family and we continue to mourn his passing on a daily basis,'' he said.

''We hope that the court will consider the impact Roberto's death has had on the family.''
