Qld police seeking help with cash find

Queensland Police are seeking help from the public to track down the owner of a large amount of cash found in Brisbane's north last year.

Police say members of the public handed over a black plastic box containing the cash and a mobile phone to police at Carseldine Police Station in August 2015.

Police would not comment on how much money was inside the box but say extensive inquiries and tests have failed to locate the owner.
