An Australian teenager has been arrested while driving a motorised chilly bin full of cannabis, with the police even deploying a helicopter to apprehend the "mobile marijuana unit".

The 17-year-old from Melbourne attracted the attention of his neighbours as he cruised the streets of his neighbourhood, 9 News reported.

The homemade contraption, which came complete with a road sign for decoration, was then tracked down by the police with the help of a helicopter unit.

Cops found cannabis prepared for sale, electronic scales and a dirty bong inside the chilly bin, which they dubbed a "mobile marijuana unit".
