Detectives are investigating a terrifying home invasion on Brisbane’s southside, where the occupants were threatened with batons, knives and a shortened firearm.

It’s understood three men, who were not known to the occupants, fled after conducting a quick search of the house on Newnham Road in Wishart.

Two women, two men and a child were at home at the time and were not injured.

Police are investigating possible links to another incident on Newnham Road near Mount Gravatt Capalaba Road on Monday October 31, where police were called to minor traffic crash and received reports a handgun had been thrown into nearby bushes.

Police located a handgun and investigations are ongoing.

The occupants of the home have no links to the traffic crash.

Police want to hear from anyone who might have dashcam footage or CCTV of either of the incidents.
