The Brazilian Government says it wants a rigorous investigation into the death of a 21-year-old Brazilian student who died after being tasered by police in Sydney.
Roberto Laudisio Curti died early on Sunday morning as police were investigating the theft of a packet of biscuits from a nearby convenience store.
He had been living with his sister and her Australian husband in Sydney since last winter while studying English.
Police say Mr Laudisio Curti was resisting arrest, but detectives are looking into whether guidelines were breached by officers who tasered him as he ran away.
In Australia, tasers are only meant to be used to protect people from violence.
