Queensland Police said the incident unfolded around 1pm on August 9 in Staplyton, Gold Coast, when three people arrived at the man’s property, reportedly in relation to the recent sale of a 2013 Nissan Pulsar online for less than three thousand dollars.

It will be alleged the group confronted the 52-year-old, demanding a refund, before tensions escalated and he was thrown from the veranda to the ground below breaking the balustrade.

Police further allege the seller was assaulted again while on the ground with part of the broken railing by one of the men, after which the group fled the scene in a Volkswagen van.

“That victim was transported by Queensland Ambulance Service (QAS) to the PA Hospital, and injuries are significant,” Superintendent Brett Jackson from Queensland Police Service (QPS) said.

“The full extent of those injuries is not yet known.

“Police investigations have identified a number of suspects in relation to this matter.”

No arrests have been made at this time.
