A man has been charged with murder after he allegedly beat an elderly man to death with a pole during a series of wild attacks in central Queensland.

Police allege a man driving a Subaru Liberty on Whitebridge Rd at North Isis, near Childers, stopped his car, got out, and punched an elderly pedestrian in the head before hitting him with a metal pole about 2.38pm on Wednesday.

The pedestrian, a 78-year-old North Isis man who was walking his dog at the time, sustained critical injuries and died at the scene.

Police allege the same suspect had less than 10 minutes earlier deliberately reversed into a Mitsubishi Pajero, before reversing into the 65-year-old male driver when he exited to look at his damaged car.

The suspect is then alleged to have punched the Mitsubishi driver multiple times before leaving the scene.

Police further allege the suspect drove to Crescent St at the intersection of Lord St in Childers and assaulted a 66-year-old man.

A 36-year-old Bundaberg West man was restrained by members of the public before he was arrested by police a short time later.

Police said none of the victims are believed to be known to the man.

He is also alleged to have been involved in an earlier crash on the Bruce Hwy at Glenorchy, when the Subaru was deliberately reversed into a Tesla, before he verbally assaulted the driver.

The man has been charged with multiple offences, including murder and attempted murder.

He will appear at Gladstone Magistrates Court via video link on Thursday.

Investigations are ongoing, and anyone with relevant vision or information is urged to contact police.
