A manhunt is under way after a woman was fatally shot on a suburban street in broad daylight.
A car has been seized as police ramp up their search for those responsible for the shooting west of Brisbane amid a homicide investigation.
Surrounding city streets were locked down and residents warned to stay indoors after the 27-year-old woman was discovered on Wednesday afternoon.
Police were called to a North Toowoomba home about 2pm following reports of a disturbance and found the woman on the footpath with multiple serious injuries.
She was rushed to hospital in a critical condition but later died.
Police do not know how many offenders were involved and have not found a weapon.
A white Toyota Camry sedan believed to be linked to the shooting has been seized, with police releasing images of the vehicle on Thursday.
"We're still seeking further information to ascertain ... how many people may have been in the area and involved in this incident," Acting Detective Inspector Brian Collins told reporters on Thursday.
Investigators are calling for any witnesses around West and Christmas Street in North Toowoomba on Wednesday from 1.30pm to 2pm to come forward.
It is understood the victim did not live at either address.
Investigators are also seeking anyone who saw the Toyota Camry in the area or nearby Gladstone Street.
Det Collins confirmed the seized sedan was under forensic examination.
Three people known to the victim have been assisting police.
Det Collins said the incident was concerning but did not believe there was any risk to the community.
"We're confident that it's not a random attack however, at this point in time, we're still trying to investigate exactly what occurred," he said.
