The 36-year-old man needed treatment for a pre-existing medical condition and voluntarily handed himself over to police outside the duplex home near Banoon train station at Sunnybank just after noon on Friday.

“It’s been peacefully resolved, which is always our aim, for everything to be peaceful,” Patrol Inspector Michelle Piket told reporters.

“And the community has been brilliant, they’ve provided all the assistance and they’ve managed to go about their lives without us having to interfere with them too much.”

The armed man was understood to be related to the woman he was holding but police would not confirm reports he also held a five-year-old boy.

Cracks and bangs were heard in the area on Friday morning with some media reporting the sounds as possible gunshots, however police said they were unrelated to the incident.

The man needed medical assistance later and voluntarily surrendered to officers about 12pm on Friday.

He was led out of the home in handcuffs, with the woman and boy walking outside a short time later.

“It’s just part of police procedure, if he has any medical issues we have him assessed,” Piket said.

“So he needed to see the QAS (Queensland Ambulance Service), not a result of any interaction with police, just a pre-existing condition.”

The man is understood to be related to the woman and boy and he is expected to face court on Saturday morning.
