Two men were assaulted and robbed before one was kidnapped from a Gold Coast basement car park, sparking a plea for dash cam footage of the incident.
Police said the men, a 24-year-old from South Australia and a 22-year-old Gold Coast man, were at a Southport apartment complex when they were approached by five men wearing balaclavas about 8pm on Wednesday.
Both men were assaulted and forced into a Mercedes Benz C63 sedan.
The 24-year-old man escaped before the Gold Coast man was taken by force from the car park.
He was transferred to another vehicle and taken to an address where police allege he was tortured - tied to a chair, assaulted and threatened with what is believed to be a firearm.
The 22-year-old suffered injuries to his face and wrists before he was released at Burbank, southeast of Brisbane, and used a ride-share operator to return to Southport.
Both men were in stable condition and treated at Gold Coast Hospital.
The Mercedes Benz was abandoned at Brighton Parade, Southport, about 9.45pm with a Nissan Maxima driven by the mask men also found in Southport.
Detective Inspector Chris Ahearn refused to comment on a motive but said it was not believed to be a random attack.
"I really don't want to go near a motive for this matter, our investigation is still live and I do not want to jeopardise it," Det Ahearn told reporters on Friday.
"It's very rare to have someone kidnapped - it's extremely concerning, but I would point out to the community that this is a targeted attack."
Police have asked anyone with dash-camera footage in the vicinity of Como Crescent, Brighton Parade, or Park Lane at Southport on Wednesday night to contact authorities.
Investigations continue.
