Constable Peter McAulay, 24, was rushed to Princess Alexandra Hospital, where he underwent surgery for serious head injuries and remained in a critical condition in an induced coma on Thursday afternoon.

Brisbane Road in Booval, where Constable McAulay was hit, reopened about 10 hours after the incident, having been cordoned off and declared a crime scene.

Police said officers spotted a stolen Volvo sedan turning into Brisbane Road about 5am. It will be alleged Constable McAulay had rolled out stingers across the road to stop the sedan, when the car swerved to avoid the spikes and hit him.

The sedan allegedly continued down Brisbane Road and turned into Vowles Street, before the occupants abandoned their vehicle and fled on foot. It will be alleged the car had been stolen from Sunnybank Hills on Sunday.

The Queensland Police Service released a statement on Thursday afternoon saying Constable MacAulay, who remained in the intensive care unit had suffered broken bones and fractures during the incident.

"Every officer and staff member of the Queensland Police Service is thinking of Constable McAulay, his family and his loved ones today," the statement said.

"The QPS would also like to thank the doctors, nurses, paramedics and other medical and support staff who have been involved in his treatment.

"The QPS is providing support to those closest to Constable McAulay and would also like to acknowledge the support being provided by the Queensland Police Union of Employees.

"It is the sincere hope of the QPS that Constable McAulay’s condition improves as he is treated for his very serious injuries."

A 16-year-old boy and 15-year-old girl have been charged with attempted murder and unlawful use of a motor vehicle. They were captured after the dog squad tracked them down near the crime scene.

"That vehicle continued travelling a short distance and the offenders left the car," Acting Superintendent Mel Adams said.

"Police officers then cordoned the scene (and) the police dog squad attended and managed to track the offenders."

Acting Superintendent Adams said officers in the "close-knit policing district" found it extremely difficult to see one of their own in hospital.

"We look after ourselves and our thoughts are with this officer and his family and we’d ask people to say a prayer for him," she said.

Both directions of Brisbane Road were initially close, along with Hamilton Street. Drivers were advised to avoid the area as delays were expected.

Queensland Police Union general secretary Mick Barnes said the incident sent shockwaves through the police community.

"The whole police family are very on edge. It could have happened to anybody," he said.

"I believe (the officer) is now in the intensive care unit and by now, his parents would've travelled down from central Queensland.

"This is a reminder, especially with National Police Remembrance Day being commemorated in Brisbane on Friday, that all of us are vulnerable.

"This officer was doing his job this morning in the most dangerous of conditions trying to keep our community safe."

Mr Barnes said he called on some of the Queensland Police Service's policies to be reviewed following recent incidents where police were seriously injured.

"There’s been two within a month," he said.

"It’s a trend where offenders know they can drive in a dangerous manner with little consequences of their behaviour."

The last incident was on September 1 where a police officer was left in a serious condition after he was hit and carried on a stolen car's bonnet for about 30 metres in Brisbane's north overnight.

Mr Barnes said his thoughts were with Constable McAulay, and his family and friends.

The Queensland Police Union has created a fund for those wishing to make a donation for Constable Peter McAulay, with all proceeds going directly to the officer.
