Two teenagers have been charged with attempted murder after a police officer was allegedly struck and dragged for several metres by a stolen car, while laying road stingers at Booval, west of Brisbane, early on Friday morning.

Pete McAulay, a 24-year-old constable from Goodna police station, is in a critical condition in the intensive care unit at the Princess Alexandra Hospital in Brisbane, after suffering critical head injuries, broken bones and fractures.

He underwent surgery earlier on Thursday and is in an induced coma in a critical but stable condition.

A 16-year-old boy and 15-year-old girl were both charged with one count each of attempted murder and unlawful use of a motor vehicle.

Queensland Police Union president Ian Leavers said they were providing as much support as possible to constable McAulay's colleagues, his family and his partner, who is also a police officer.

"I've had calls from all over Australia today, their thoughts are with Pete, who simply is where he is now cause he turned up to work trying to do the right thing," Mr Leavers said.

"We want Pete to get better and we're praying for him, but we want justice to be served as well."

Mr Leavers said the young constable was only starting his career as an officer after graduating from the police academy in 2014.

"He just loved his job and loved turning up to work," he said.

"He's respected by all his colleagues and those who know him have certainly been touched by him.

"This is a reminder for all police on the sacrifice and what police do.

"They put their lives on the line, day in day out and sadly, this is one of the dangers."

Acting Superintendent Melissa Adams said the officer was mowed down while laying road stingers to stop the stolen car.

"During that deployment, a police officer has been struck by the vehicle and sustained significant injuries — that vehicle continued travelling for a short distance and the offenders left the car," she said.

She said it was difficult for police to see one of their own injured.

"We are a very close knit policing district — we look after ourselves, and our thoughts are with this officer and his family," Acting Superintendent Adams said.

"We ask people to say a prayer for him."

Police found the vehicle abandoned on Vowels Street.

Troy Carpenter, 52, said he heard police sirens early this morning.

"I initially disregarded it because I live on a main road and I didn't think it was anything unusual," he said.

"When I came out to have a look I was quite shocked to see all the police and to know that somebody has been hurt for such a ridiculous thing — it's terrible."

This latest incident comes just 24 hours before police officers gather at North Ipswich Oval on Friday to march and remember their fallen colleagues as part of Police Remembrance Day on September 29.
