Police are investigating after a man was assaulted during a burglary at a residence in Gladstone last night.

Preliminary information suggests four young males entered the premises on Streeter Street in Clinton around 10pm.

They demanded money from the residents, a 45-year-old man and a 40-year-old woman.

One of the men then produced a metal bar and struck the male victim across the head.

A struggle ensued and the injured man managed to force the intruders out of the home who then fled the scene.

The four men are described as Caucasian in appearance, one being around 190cm tall with a thin build and short brown hair, and the other three around 158cm tall with medium buiwhte-faceslds.

All four were wearing white face masks and dark long sleeved clothing.

The male victim was transported to Gladstone Base Hospital where he has undergone surgery for a large laceration to his forehead.

The woman was uninjured.
