Police have launched a search and rescue operation in the Redlands area on Brisbane's southside to locate missing 43-year-old Toowoomba man, Derrick Hearne.
Derrick, pictured, was reported missing on Saturday, October 26, after leaving a Cambooya property on a Harley Davidson motorbike.
The motorbike was located abandoned near bushland along Chelsea Road in Ransome at approximately 2am today, October 27.
A search and rescue operation commenced, with police and State Emergency Services volunteers searching bushland and creek areas in the Redlands.
