Man shot dead by police in Mackay, Queensland

Police attended an address on Bridge Street about 2.30pm on Monday in response to reports a man had threatened self-harm.

Negotiators were called in to attend the scene and speak to the man, police said.

An emergency declaration under the Public Safety Preservation Act was declared about 4.10pm and an exclusion zone was established on Bridge Street, Hume Street and Streeter Avenue while police continued to negotiate with the man.

Police said officers had been confronted by a man allegedly armed with a firearm.

The 24-year-old man allegedly advanced at officers and was subsequently shot just after 5pm.

He was transported to Mackay Base hospital in a critical condition, where he later died.

A crime scene has been established and the ethical standards command is investigating.

The investigation is subject to oversight by the Crime and Corruption Commission.
