A Queensland man is believed to have been stabbed to death on a street in Underwood, south of Brisbane, just after 1am on Friday.

Aiden Rhys Bower-Miles was unresponsive when emergency services arrived at Fermont Rd and was later pronounced dead.

Early investigations suggest there was a disturbance at the end of the street and the 20-year-old was walking back to his home when he was stabbed.

“How many times do we have to say don’t carry knives,” Detective Superintendent Brendan Smith said.

“These things wouldn’t happen if people didn’t carry knives.”

A homicide investigation has now been launched by police.

It’s too early to tell if the incident is gang-related, Smith said, but “it doesn’t appear to be”.

The area was declared a crime scene as investigations continue.

There are no suspects at this stage.

Anyone with information, CCTV or dashcam footage showing a dark-coloured SUV in the area at the time is asked to come forward.
