In what was a scathing critique of at least five police officers, NSW Coroner Mary Jerram said the officers involved in the death of Roberto Laudisio Curti earlier this year acted like "schoolboys in Lord of the Flies" with little or no understanding of what threat or crime was supposedly being averted by the chaotic and violent struggle.

Mr Curti was chased by police down Pitt Street in Sydney city centre, tasered several times, sprayed with almost three cans of OC spray, handcuffed and restrained by seven officers on the ground during the incident in March this year.

Commissioner Andrew Scipione said he accepted the Coroner's recommendations and said the force would "carefully examine" the issues Ms Jerram asked them to.

However, Mr Scipione said he stood by the use of Tasers as a weapon for officers, saying they "save lives".
