A major police investigation is under way in Brisbane after a man was stabbed in an inner-city apartment early this morning.

The 39-year-old man was stabbed and left for dead in a hallway.

One local said they saw blood in the lift in the Bowen Hills apartment block at 5am.

Police say the West End man was among family and detectives are still trying to figure out where it all went wrong.

“My understanding is that the victim has attempted to remove himself from the crime scene,” Acting Detective Inspector Murray O’Connell said.

“He was taken to the Royal Brisbane Hospital but sadly he succumbed of his injuries and passed away a short time later.”

A 22-year-old man and 45-year-old woman were taken into police custody.

“We believe that they’re extended family members, but we’re still trying to work that out at the moment, just the dynamics of the family,” O’Connell said.

“The knife has been found, what we believe is the weapon that was used in this attack.”

Police say the three had been out socialising earlier in the evening, with investigators working to determine how this night turned so violent

“I would hope there would be some charges soon, but it’s too early to say at this stage,” O’Connell said.
