It is a dramatic heist that left the tongues wagging with its sophistication and the amount of money involved.
Police investigators investigating the heist believe that the three suspects could have brought their engineering knowledge to carry out the heist.
Alfred Munene is an electrical engineering graduate while his brothers Charles and Julias are agricultural engineering students.
Elaborate wiring was used for illumination while metal stands prevented the tunnel from caving in.
20 million shillings have already been recovered and police are still carrying out investigations that will give them leads to where the rest of the money is.
The three suspects have pleaded not guilty.
