Ananova:

A gang of prisoners tunnelled out of a Brazilian jail - only to emerge in the prison yard.

The 67 men emerged just 30 centimetres short of Timoteo Prison's main perimeter wall.

They had painstakingly planned the break out but failed to build the tunnel long enough.

As they emerged from the tunnel, they found guards already waiting to take them back to their cells, Jornal da Globo reports.

A police spokesman said: "They were so frustrated and we could not hold our laughter, they were really dumb!"
