A 19-year-old man has been shot by police north of Brisbane after his mother called officers to conduct a welfare check.

Police said officers were called to Akebia Street in Arana Hills about 12:30pm and were attempting to speak with the man when an altercation occurred.

Regional crime coordinator Andrew Massingham said police would allege the man produced a “large kitchen knife” while speaking to officers on the lower level of the home.

“As a result there has been two shots fired by one of the male officers,” he said.

Superintendent Massingham said the man was struck twice in the abdomen.

Officers provided first aid at the scene before he was taken to the Royal Brisbane Hospital in a critical condition.

Superintendent Massingham said the call for assistance had come from the man’s mother, who was present during the shooting, and that the man had previously received mental health treatment.

“Mum is distressed, she’s traumatised,” he said.

Superintendent Massingham said a taser was also deployed during the incident, which will be the subject of an Ethical Starnds Command investigation.

“The timing of that in terms of when the shots were fired will be the subject of the ongoing investigation,” he said.

He said the officers had body-worn cameras, which were operating at the time of the shooting.

Superintendent Massingham said the police officer who fired the shots was a first-year constable.

“It is traumatic for all involved and that young man is feeling it right now,” he said.

A crime scene has been established.
