UPDATE 12.30PM: A 29-year-old Ipswich woman is in custody and a 34-year-old Burpengary man is under police guard in hospital after being caught by police near Killarney last night.
The couple was wanted in relation to a number of armed robberies in south-east Queensland, with the male offender being shot in the leg several times by police when intercepted on Spring Creek Rd.
A police spokesman said following "extensive inquiries into a number of serious matters", police started to follow a vehicle at Aratula last night.
"Officers intercepted the vehicle using stingers near Killarney around 9.30pm," the spokesman said.
"In the circumstances that followed, a man in the vehicle was shot by police. It will be alleged the man was armed with a firearm.
"The man is in the Princess Alexandra Hospital with gunshot wounds to one arm and a leg.
"His injuries are believed to be non-life threatening."
The spokesman said the female passenger in the vehicle was taken to Warwick Hospital for precautionary treatment but was later released.
She has been charged with one count of armed robbery in relation to an incident at Kedron on July 23 and is due to appear in the Toowoomba Magistrates Court this morning.
An officer who sustained an injured wrist during the arrest last night is being treated in the Ipswich Hospital.
Investigations are continuing.
The circumstances of the shooting will be investigated separately by the QPS Ethical Standards Command.
Assistant General Secretary of the Queensland Police Union Denis Sycz said the officers acted appropriately for their own safety.
"Police defended their own lives and performed professionally, appropriately and courageously," Mr Sycz said.
"Police did a fantastic job and we're very lucky no officers were seriously injured.
"It could have been a lot worse."
