A woman has died after a high-speed collision with a car that was allegedly stolen at gunpoint on Queensland's Sunshine Coast.
The 52-year-old was trapped inside her Nissan Micra following the crash with a Mercedes hatchback at Burnside in Nambour about 7am on Friday.
Paramedics were unable to revive her.
The crash happened about five hours after the Mercedes was allegedly stolen from a home in Landsborough, about 30km away.
A man in his 20s allegedly used a firearm during the robbery, Detective Senior Sergeant Craig Mansfield said.
The car was later seen driving erratically in Burnside and was allegedly on the wrong side of the road when it collided with the woman's vehicle.
The man fled on foot and was chased by "good samaritans" who followed him to a nearby property and blocked him from escaping in a second vehicle, Det Sen Sgt Mansfield said.
Police arrested him soon after.
Det Sen Sgt Mansfield praised the "absolutely heroic" members of the public who rushed to try to save the woman, as well as the efforts of the people who pursued the driver of the other vehicle.
He called for anyone with information or dash cam video to come forward.
On Friday night, police charged a 26-year-old Caloundra West man with dangerous driving causing death while adversely affected by an intoxicating substance, driver callous disregard to deceased, enter dwelling with intent, unlawful use of a motor vehicle, armed robbery, possession of shortened firearm, possession of a dangerous drug (methylamphetamine), carry loaded firearm in public, possession of a weapon whilst under the influence of liquor or a drug, possession of explosive (ammunition), possession of utensil (pipe) and disqualified driving.
The man will appear via video link before the Hervey Bay Magistrates Court on Saturday.
