A 2006 NISSAN Patrol stolen from a Talgai property in late May was found by Warwick police near the Lyndhurst Lane bridge across the Condamine River.
The stolen vehicle included $10,000 worth of tools.
Detective Sergeant Darren Tamblyn said police received information from the public that the vehicle was near the river on Wednesday.
"A 16-year-old boy, who was fishing in the river at the time, was dealt with through the Juvenile Justice Act," Det Sgt Tamblyn said.
As a result of further police investigations, all of the tools were later found at a Warwick residence.
There was no damage to the vehicle and tools, which have now been returned to the property owner at Talgai.
