A third person has been charged after a "targeted" shooting in Brisbane city.
Police responded to reports of gun shots fired in the CBD before 11pm on Saturday night.
Three people were injured in what police believed was a targeted attack.
The alleged offenders fled the scene and travelled to Brisbane's southwest where they set fire to the vehicle they were travelling in just after midnight.
Two men, aged 19 and 20, were arrested and charged with four counts of attempted murder, and a string of other weapons and driving offences.
A third person - a 22-year-old man - has now been charged with 16 offences including four counts of attempted murder.
Police said the 22-year-old was arrested at a property in Darra on Monday afternoon.
He has been denied police bail and is set to appear in Brisbane Magistrates Court on Tuesday.
